This invention relates to a system and method for creation and automatic deployment of personalized, dynamic and interactive voice services relating to subscriber corporate analysis related information, including information derived from on-line analytical processing (OLAP) systems. More specifically, the invention relates to a system and method that enable personalized delivery of corporate analysis-related information in real-time, via natural language voice communication with a voice-enabled terminal device.
Various systems exist for enabling companies to analyze corporate performance. Indeed, that type of information has been the backbone of the decision support industry. In such systems, decision support systems review information about the company to determine how the company is performing based on any number of criteria. These systems, however, require a person to log onto the network to initiate a report and then to wait for the report to be returned. These systems do not provide a way for the corporate analyst to meaningfully receive information without the difficulty of having to periodically request updates. Moreover, once the information is received, the corporate analyst may desire to take responsive action.
These and other drawbacks exist with current systems.
An object of the invention is to overcome these and other drawbacks in existing systems and methods.
Another object of the invention is to provide a system and method for providing real-time, interactive information about corporate information.
Another object of the invention is to provide systems and methods for interactive real-time transmissions of information about corporate analysis and performance and that enable the user that receives the information to react with a request during the transmission.
These and other objects of the invention are accomplished according to various embodiments of the invention. According to one embodiment of the invention, a subscriber to the corporate analysis service is presented with information about corporate performance and provided with real-time, interactive user inputs to enable the corporate subscriber to react to the performance information. Corporate analysis information as used herein should be understood to include any information about a company, including partnerships, coops, individual businesses, corporations (either private or public), non-profit organizations, government agencies, and schools, among others. Corporate analysis information may be desired about any entity that makes money or offers a product or service. Information collected may include profits, sales, marketing, costs, inventory, availability from vendors, margins, pricing, relative performance, market share, price to earning ratio, market capitalization, stock price, stock trading volume, and any other information that a corporate person might be interested about relative to a particular corporate entity.
Information about the corporate analysis performed is communicated to the subscriber. Options for responding to the corporate analysis may also be communicated to a subscriber in a real-time, interactive format, thereby allowing a subscriber to react to corporate analysis information in response to the corporate analysis information.
Another embodiment of the invention relates to a system and method for creation and automatic deployment of personalized, dynamic and interactive voice services, including information derived from on-line analytical processing (OLAP) systems and other data repositories. The system and method enables the ability to capture user selections to facilitate closed-loop transaction processing and processing of other requests. One aspect of the invention relates to an interactive voice broadcasting system and method that enables analytical reporting and advanced transactional services via the telephone or other voice-enabled terminal device. One advantage of the invention is that a voice service may leverage the power of OLAP or other data repository systems and provide critical information to the user, in a timely fashion, by phone. Another advantage of this method and system is that it provides a user with the opportunity to immediately act upon information received during a interactive voice broadcast.
A voice service is created and can have many users subscribed to the voice service. Each user can specify personal preferences for the content and presentation of the contents for a voice service. The specification of the elements of a voice service may be done using a set of interfaces (such as GUIs) that take the form of a voice service wizard.
A voice service includes one or more Dialog elements. Dialog elements may include one or more of Speech elements, Input elements and Error elements. An Input element may include a Prompt element and/or an Option element. An Input element enables the system to request input from the user, capture the input and direct the call flow based on the user's input. An Option element associates a key (e.g., on a telephone touch pad dial) with a destination Dialog that is executed when that number is pressed by a user during an interactive voice broadcast. A Prompt requests a user to enter numeric or other information. An Input element may enable a user to request, during an interactive voice broadcast, a transaction, a service or other requests. The term transactions, services and requests are to be interpreted broadly.
According to one embodiment, the user's responses to Input elements are stored during an interactive voice broadcast and, during or after the voice broadcast, the stored information is processed by the system or is passed to another system or application for processing. The transaction (or other request) processing can be accomplished either in real-time, during the voice broadcast, or after the interactive voice broadcast is completed. The results or confirmation of a transaction or other request can be provided to the user during the call or subsequently.
Once a voice service is created, the system monitors predetermined conditions to determine when the voice service should be executed. Each voice service is executed when one or more predetermined conditions are met as specified during creation of the voice service. For example, a voice service may be executed according to a predetermined schedule (time-based) or based on a triggering event (e.g. one or more conditions are met based on the output of an OLAP or other report).
When the predetermined condition is satisfied, the voice service is executed. Executing a voice service, includes the steps of generating the content specified by the voice service and the user preferences. Some users may have identical personalization options and, thus, a single call structure may be generated for a group of users with identical personalization options. The content of the voice service includes the information that is to delivered to users of that voice service, and the Input to be requested from the user, among other things. The content may include, for example, static text messages, dynamic content (e.g. text based on information output from an OLAP report, other database or other sources) or blended text (e.g. static text combined with dynamic content).
This and other content are formatted in an Active Voice Page (AVP). An AVP contains the call structure and data. The AVP contains data at various hierarchical levels that are defined by the Dialog elements defined for each voice service. The active voice pages are used to help govern the interaction between the call server and the user during an IVB. According to one embodiment, the content is formatted, into an AVP e.g., using XSL stylesheets so the AVP is in an XML-based language. According to one embodiment, the XML-based language used is a novel language referred to as TML (discussed below). The AVP is sent to a call server along with style properties for each user. The style properties of a user help determine the behavior of the call server during an interactive voice broadcast. A unique AVP is generated for each user scheduled to receive a voice service.
When a user is called by the call server, information is passed through a T-T-S engine and delivered to the user through a voice-enabled terminal device. Preferably, the structure of each call is dynamic, driven by current data values and is personalized based on a user profile established during subscription to a voice service. During a typical interactive voice broadcast, a synthesized, natural sounding voice greets the recipient by name, identifies itself, provides information relevant to the user and enables a user to provide input back to the system.
An IVB is a voice-enabled interaction with a user having a dynamic structure controlled by the AVP for the particular user. The IVB may be delivered using real-time, on-the-fly speech generation. During an IVB, information is exchanged between the call server and a user according to the AVP. The system executes dialogs by reading messages to the user and, eliciting input from the user. For example, the user may press buttons on a telephone touch pad dial to select an option or to provide numeric or alphanumeric input. Each response provided by a user may transfer control of the IVB to a different part of the AVP.
During or after the IVB, the user's responses may be processed by the system or other applications. The AVP may contain pointers to other applications and embedded statements such that when a user exercises an option, the system performs a requested operation and returns the results to the user during the IVB. For example, by exercising an option, a user may request that a real-time database query be performed. When the user selects such an option, control is shifted to a portion of the AVP that contains an embedded SQL statement that is made against a database.
When a user has worked through selected dialogs of the AVP, the IVB is terminated. That is, a user likely will not work through all of the available dialogs during an IVB. Rather, the user's inputs and option selections determine which the available dialogs are encountered during any given IVB.

a-10d illustrate examples of content that may be presented to a corporate analysis subscriber according to an embodiment of the invention.
The present invention is described in relation to providing interactive, real-time information modification related to corporate analysis information, and more particularly to real-time, interactive voice communication of corporate analysis information that enables subscribers to react in a meaningful manner through a two-way communications terminal device at which the telephone communication is received.
For purposes of explaining the present invention, an example of a specific embodiment of the present invention is set forth. A vice-president in charge of sales may be concerned about inventory levels to make sure that when she makes a sale to a customer, there is adequate inventory in stock to fulfill the order in a timely fashion. Accordingly, a data warehouse containing inventory information may be stored and accessible by a monitoring system of the present invention. Then the vice-president may be allowed to subscribe to a service that monitors inventory. The subscriber may select multiple types of output, including a daily or other periodic update, that generates a report periodically and presents options to enable the subscriber to react, e.g., by ordering more inventory, instructing manufacturing to increase production, contacting the vice-president of manufacturing to request overtime production or any other reaction that may be related to the information provided. Also, the subscriber may desire to have that information on an alert service that notifies the subscriber when the inventory falls below a predetermined level.
Accordingly, the subscriber subscribes to one or more services related to inventory and specifies the manner and conditions upon which the service is to be output to the user and the device and personal information at which the user desires to receive output. Information for a user may be specified, including specifying personal preferences to content (e.g., the filters to be applied to the data such as only providing inventory information about a particular product rather than all products) and presentation of content (e.g., the type of device at which information is to be received, the tone and pitch of the voice output to the device, etc.).
Corporate information may be created and stored into a database, such as a data warehouse according to existing corporate data storage techniques. Additionally, subscriber personal information may also be stored, such as contact information, authorization for certain types of data, preferences for filters to be applied generally, formatting preferences, etc. Personal information may include the name of the user, home and office addresses and telephone numbers for the user, and any methods for contacting the user, including a pager number, a personal digital assistant address, or other interactive communications device, and other information.
The voice service monitors predetermined conditions related to the corporate analysis information requested to determine when the voice service is executed. In this example, a user may set a corporate analysis service to be processed if sales for a particular product drops 5% in a day or if inventory for a particular product in a warehouse falls below a predetermined amount. The voice system monitors the predetermined conditions and notes when the conditions are satisfied, such as by periodically (according to a monitoring check rate) checking these conditions through processing a report using an OLAP system against a data warehouse. When the predetermined conditions are satisfied, the voice service is then executed.
Content is generated by the voice service, including content based on user preferences. Content may include options for reacting to the information from the corporate analysis report. For example, the subscriber in charge of inventory may order more inventory in response to a notice that inventory has fallen below predetermined levels. Also, a subscriber may contact another person to request additional information, may “drill down” to determine more detailed information about the request, may hold a shipment, change shipment schedules, etc.
A call structure is created based on content, and sent to a call database. A call structure may contain content as dialog element comprising static content and dynamic content. According to this example, static text may comprise a greeting indicating the service being provided such as “Hello [dynamic content], this is Telecaster and we are providing your inventory alert. You only have [dynamic content] in inventory. Would you like to [dynamic content].” The dynamic content may comprise any information generated from the database upon processing of the service. Here the dynamic content may be “Steve,” “four hundred gross of bottle rockets,” and “Order another thousand gross, press 1, set a new service to notify you when another level is reached, contact Bob the warehouse manager.”
A call server queries the call database for content, and places a call to the user. Information passes through a text-to-speech engine is delivered to a user. According to this example, a telephone communication is established with the user, and the static content and user inputs may be communicated by speech output to the user.
A user's response to information is stored and processed. A user may wait on the telephone while the response is processed, or may hang up and be informed letter about the processing results. The above discussion is directed to a specific embodiment of the present invention. A general description of the present invention will now be described below.
At step 910, a corporate analysis voice service is created. A user is subscribed to the corporate analysis voice service at step 912. At step 914, the corporate analysis voice service monitors predetermined conditions. At step 916, the corporate analysis voice service determines whether to execute. Content based on predetermined conditions is created at step 918. At step 920, a call structure is created, and at step 922, the call structure is sent to a call database. At step 924, a call server queries a call database. A call server places a call at step 926. At step 928, information passes through a text-to-speech engine, and information is delivered to a user at step 930. At step 932, user responses are stored and at step 934, user responses are processed. The flowchart of
At step 910, a corporate analysis voice service is created. A corporate analysis voice service enables a user to receive real-time, personalized, dynamic voice services for corporate-related information based on corporate performance and transactional data and corporate user personal information. Other information may also be used.
At step 912, a user may be subscribed to a corporate analysis service. Within the service, a list of filters, templates and other information desired to be monitored may be input by the user. A service may be set up using MicroStrategy's existing OLAP technology to monitor data content in a data warehouse or other database system.
Also, certain corporate information may be subscribed to by a system administrator. For example, a corporate may sign all of its sales representatives to a service that notifies the sales representative when sales in that representative's territory falls below a predetermined performance level. The inputs that may be provided to the sales representative may include scheduling a conference call with a sales assistance staff, scheduling appointments with the representative's stores, processing a complaint to the manufacturing department about the quality of goods, etc. A service may be established according to the system and method described with respect to the system in
In addition to the subscription, the service may either access or request personal information. Personal information may include the name of a user, the sales territory, the corporate title, the corporate responsibilities, assistant's information, geographic location, data access privileges and other corporate related information to be able to determine the appropriateness of a service for the subscriber and to be able to properly personalize the information based on the subscriber's corporate positions. According to an embodiment of the invention, personal information includes information that enables interactive, real-time transmission of information about a corporate analysis information output to a user. According to an embodiment of the invention, personal information may provided once by a user and saved for later use. Every time a user subscribes to a service of the present invention, personal information may be reused. A user may update personal information as desired. According to an embodiment of the invention, personal information may be received from a user and stored into an OLAP data warehouse as described below with respect to the system of
At step 914, a corporate analysis voice service monitors predetermined conditions as set forth in corporate analysis service and personal information. Changes, increases, improvements, variations and other information may be used as alert conditions that initiate an alert-based service. Also, it may be desired to provide a scheduled report that is processed periodically and generated regardless of whether any trigger or alert conditions are satisfied. Also, an initiation request may be received to process a service regardless of the schedule. For example, an administrator may decide that he wants to send a voice service on sales to all representatives a half hour before a meeting and may initiate the voice services regardless of the schedule on which they are normally processed.
According to an embodiment of the invention, a user may define in personal information what information is to be monitored. Monitored information may any of the corporate data or additionally, any information or data that may have an effect on corporate information. For example, a sales leader may want to know that weather in South Dakota is forecast to be extremely warm for the fall and therefore, change the relative proportion of wool to light sweaters shipped to stores in that region. Also, the vice-president of manufacturing may desire to know that prices of a key ingredient have dropped dramatically over the last several months, but that a wire report indicates a potential increasing trend. In response to that report, the VP may desire to purchase now rather than waiting until prices go higher. Therefore, the corporate analysis information may also include information and data that may affect the performance of a particular corporate entity. To do so, the information stored for the service may include news feeds and other data sources containing the information to be monitored that relate to corporate analysis. Any information available in the database may be used to create a monitoring report to be processed in the corporate analysis services. Other manners of monitoring information may also be used.
According to an embodiment of the invention, corporate analysis information may be stored on a database, which in turn may be operatively connected to other databases with information that may effect corporate performance, although the information may all be stored in a single database, Other databases may include corporate news, stock analyst recommendations and reports, weather information and forecasts, etc. Corporate analysis information services may be processed against the database in a number of fashions on a predetermined basis, such as, by way of example only, every five minutes. According to an embodiment of the invention, information may be stored into an OLAP data warehouse accessible by system as described below with respect to
At step 916, a corporate analysis voice service may determine whether to execute the voice system. If predetermined conditions are not satisfied, a corporate analysis voice system may return to monitoring predetermined conditions at step 916. If predetermined conditions are met, content may be generated at step 918.
At step 918, content is generated based on corporate analysis information, personal information, predetermined conditions, and, corporate analysis updates. Additionally, user inputs for modifying reacting to the information provided may also be generated with inputs includes those described above.
According to an embodiment of the invention, user inputs may be determined based on predetermined options set up by the service creator. Also, certain options may be determined based no database queries. Databases with other information, such as source databases, may be reviewed to present options. For example, for a standard item, when inventory is low, various vendor databases may be accessed to determine availability and price to enable the subscriber to choose to reorder inventory from the best available supplier at that particular moment.
At step 918, content from corporate analysis reports and options may be generated. The content may include the most likely reactions or even queries to determine the reason for a particular report. For example, if sales drop 5%, the system may present options to enable the user to determine the cause of the drop in sales, such as drilling down to hear sales by region, representative, day, store, etc. Also, the user may be enabled to initiate a real-time query to hear a weather report for a region. For example, if the sales representative is selling sleds and sales are poor, the representative may desire to hear a weather report from various regions to determine if the weather is affecting sales. The sales representative may also desire to contact a complaints database. Other examples of queries that may be requested may also be implemented. Indeed, one option may be the initiation of one or more other services.
At step 920, a call structure may be created. According to an embodiment of the invention, a call structure may comprise static content and dynamic structure. Static content may be static text which conveys information to a user. Dynamic structure may be dynamic text which presents the results of processing a service and user inputs for a user to interact. User inputs may comprise user options and user prompts. User options may define what information a user may receive when a user presses a particular touch pad number. A user prompt may be used to specify a question that a user may be asked to be prompted for user information, including security information, for example.
At step 922, call structure is sent to a call database. A call database may be any type of conventional database that can store information.
At step 924, a call server may access a call database. A call server may access a call database for current call requests, such as provided in a system described below with respect to
At step 926, a call server may place a call to a user. A call to a user may be established to allow a user to receive information in real-time and to interact with the information. According to an embodiment of the invention, communication may be established through a telephone or other device which allows voice interaction. Other types of communication may also be used.
At step 928, information may pass through a text-to-speech engine. A text-to-speech engine permits information to be communicated to a user via a synthesized voice. Other manners for converting information may also be used.
At step 930, content may be communicated to a user. Communication of content may allow a user to receive content and to select user inputs. Other manners for communicating content to a user may also be used.
According to an embodiment of the invention, content communication to a user may include prompting a user to select from various user inputs, including user options and user prompts, to react to the corporate analysis information.
In one embodiment, the content generated may be voluminous and therefore, the content may parsed to generate a highlighted message. With the highlighted message, the user may be presented with the option of selecting to have additional information in a more detailed format to be generated and sent over another channel, such as via email, fax, Excel spreadsheet, etc.
At step 932, user responses may be stored. User responses may be instructions to react to the corporate analysis information. With real-time, interactive communication, a user may receive information, and may send instructions to react to corporate analysis information. User responses may be stored in a database, thereby allowing electronic storage of user responses. According to an embodiment of the invention, user responses may be stored in an OLAP data warehouse such as one described below with reference to
At step 934, user responses may be processed. Processing user responses may cause actions to be taken according to instructions received from a user. Orders may be placed, advertisements created, marketing strategies employed, or any other actions. Processing user responses may cause an identified individual to be notified such as an inventory manager.
a-10d illustrate content for real-time, interactive communication with a user.
b) describes an voice page that may be provided if the user selects choice 2 to lower the price. The input for page 2 may include various price changes that the user may input.
The corporate analysis performed may be applied to various fields, information, and uses. For example, manufacturing quality statistics may be monitored to provide alerts to users when certain predetermined quality levels are not being met. In response to these alerts, an administrator or manufacturing manager may be presented with various options to respond to the problem, such as halting the assembly process, modifying various inputs, etc.
In another example, competitive win rates may be monitored to determine when the corporations performance exceeds or drops below certain predetermined levels.
In another example, the corporate analysis system may be applied to situations in which leads are generated in a database. Sales managers may desire to be notified when one of their sales representatives inputs a new lead in a lead database, for example.
In other embodiment, an event manager for a corporation may desire to be informed when various event registration thresholds are met, or when certain invitees register. They may then be presented with an option to contact that representative to initiate a personal follow-up or otherwise respond to that information.
The corporation may also desire to monitor phone or other internal costs for various levels of usage to make sure that those usages do not get out of hand. An administrative manager within the corporation may then be notified about the usage and be presented with various options, including shutting down certain user's privileges, etc.
A system for enabling this technology is described. Specifically, the database information may populate an OLAP database with the interactive calling being provided by the call builder module.
According to one embodiment of the present invention, a system is provided for automatic, interactive, real-time, voice transmission of OLAP output to one or more subscribers. For example, subscribers may be called by the system, and have content delivered audibly over the telephone or other voice-enabled terminal device. During the IVB, information may be exchanged between the system and a subscriber. The system conveys content to the subscriber and, the subscriber may respond by pressing one or more buttons on a telephone touch pad dial (or other input mechanism) to hear more information, to exercise options, or to provide other responses. This interaction shapes the structure of a basic exchange between the system and the subscriber. During or after the call is terminated, the subscriber's responses may be stored and processed (e.g., by other applications).
According to one embodiment of the present invention, a method for automatic, interactive, real-time, voice transmission of OLAP output to one or more subscribers is provided.
After a voice service is created, users may subscribe or be subscribed to the voice service (step 120), for example, by using a subscription interface. According to one embodiment, users may subscribe to an existing voice service over the telephone or by web-based subscription. A user may also be subscribed programmatically. In other embodiments, a user may subscribe to a voice service via electronic mail. Not every voice service created in step 110 is available for subscription. More specifically, according to another embodiment, only a user with appropriate access, such as the creator of the service, is allowed to subscribe himself or others to a service. Such a security feature may be set when the voice service is created.
In step 130, a scheduling condition or other predetermined condition for the voice services is monitored to determine when they are to be executed. That is, when a voice service is created or subscribed to, the creator or user specifies when the voice service is to be executed. A user may schedule a voice service to execute according to the date, the time of day, the day of the week, etc. and thus, the scheduling condition will be a date, a time, or a day of the week, either one time or on a recurring basis. In the case of an alert service, discussed in more detail below, the scheduling condition will depend on satisfaction of one or more conditions. According to one embodiment, the condition(s) to be satisfied is an additional scheduling condition. According to another embodiment, to another embodiment, a service may be executed “on command” either through an administrator or programmatically through an API. Scheduling of voice services is discussed in more detail below.
The method continues monitoring the scheduling condition for voice services until a scheduling condition is met. When a scheduling condition is met, that voice service is executed as illustrated in, for example, step 140. The execution of a voice service involves, inter alia, generating the content for the voice service, and structuring the voice service to be interactively broadcast through a call server. The execution of a voice service is explained in detail in conjunction with

According to one embodiment, a voice service is constructed using service wizard. A voice service is constructed using several basic building blocks, or elements, to organize the content and structure of a call. According to one embodiment, the building blocks of a voice service comprise elements of a markup language. According to one particular embodiment, elements of a novel markup language based on XML (TML) are used to construct voice services. Before explaining how a telecast is constructed, it will be helpful to define these elements.
The DIALOG element is used to define a unit of interaction between the user and the system and it typically contains one or more of the other elements. A DIALOG can not be contained in another element.
The SPEECH element is used to define text to be read to a user.
The INPUT element is used to define a section of a DIALOG that contains interactive elements, i.e., those elements that relate to a response expected from a user and its validation. An INPUT element may contain OPTION, PROMPT and ERROR elements.
An OPTION element identifies a predefined user selection that is associated with a particular input. According to one embodiment, OPTION elements are used to associate one or more choices available to a user with telephone keys.
A PROMPT element defines a particular input that is expected. According to one embodiment, a PROMPT element defines that a sequence or number of key presses from a telephone keypad is expected as input. Unlike an OPTION Element, a PROMPT Element is not associated with predefined user selections.
The PROMPT and OPTION elements may also be used to request user input using natural language. According to one embodiment, speech recognition technology is used to enable a user to respond to a PROMPT element or to select an OPTION element verbally by saying a number, e.g., “one.”. The verbal response is recognized and used just as a keypress would be used. According to another embodiment, the user may provide a free form verbal input. For example, a PROMPT element may request that a user enter, e.g., the name of a business. In response the user speaks the name of a business. That spoken name is then resolved against predetermined standards to arrive at the input. Word spotting and slot filling may also be used in conjunction with such a PROMPT to determine the user input. For example, a PROMPT may request that the user speak a date and time, e.g., to choose an airline flight or to make a restaurant reservation. The user's spoken response may be resolved against known date and time formats to determine the input. According to another embodiment, a PROMPT is used to request input using natural language. For instance, in conjunction with a voice service to be used to make travel plans, instead of having separate PROMPT elements request input for flight arrival, departure dates and locations, a single natural language PROMPT may ask, “Please state your travel plan.” In response, the user states ‘I'd like to go from Washington D.C. to New York city on the 3rd of January and return on the 3rd of February. This request would be processed using speech recognition and pattern matching technology to derive the user's input.
The ERROR element is used to define the behavior of the system if a user makes an invalid response such as touching a number that has not been associated with an OPTION element, or entering input that does not meet the criteria of a PROMPT element. A SYS-ERROR element defines a handler for certain events, such as expiration of the waiting time for a user response.
The FOR-EACH element is used to direct the system to loop through a list of variables e.g., variables contained in a database report, or variables from a user input, to dynamically generate speech from data.
In addition to the elements described above, there are two features that maximize an administrator's ability to design voice services. Call Flow Reports enable an administrator to generate the structure of a call based on the content of an report e.g., from an OLAP system or other data repository. For example, the options presented to a user in a PROMPT element may be made to correspond to the row of a data report. According to one embodiment, report data is converted into options by application of an XSL (extensible style sheet language) style sheet. The result of this application is inserted into the static call structure when the voice service is executed.
The use of an XSL style sheet is a feature that maximizes an administrator's voice service building ability. As discussed above, they are used to create dynamic call structure that depends on data report output. They may also be used to generate a text string that comprises the message to be read to a user at any point in a call.
A method for creating a voice service according to one embodiment will now be explained in conjunction with
According to one embodiment, in step 210, a voice service is named and a description of the voice service provided. By providing a name and description, a voice service may be uniquely identified. An interface is provided for prompting input of the name of the service to be created or edited. An input may also be provided for a written description. An open typing field would be one option for providing the description input. According to another embodiment, if an existing call service has been selected to edit, the service name field may not be present or may not allow modification.
In step 220, conditions for initiating the service are selected. This may include selecting and defining a service type. At least two types of services may be provided based on how the services are triggered. A first type of service is run according to a predetermined schedule and output is generated each time the service is run. A second type of service, an alert service, is one that is run periodically as well, however, output is only generated when certain criteria is satisfied. Other service types may be possible as well. In one embodiment the administrator is prompted to choose between a scheduled service or an alert service. An interface may provide an appropriate prompt and some means for selecting between a scheduled service and an alert service. One option for providing the input might be an interface with a two element toggle list.
In one embodiment, a set of alert conditions is specified to allow the system to evaluate when the service should be initiated if an alert type service has been selected. In one embodiment, a report or a template/filter combination upon which the alert is based is specified. Reports and template/filter combinations may be predefined by other objects in the system including an agent module or object creation module. According to one embodiment, an agent module, such as DSS agent™ offered by MicroStrategy, may be used to create and define reports with filters and template combinations, and to establish the alert criteria for an alert service. According to another embodiment, an interface is provided which includes a listing of any alert conditions presently selected for the voice service. According to this embodiment, the interface may comprise a display window. A browse feature may take the user to a special browsing interface configured to select a report or filter-template combination. One embodiment of an interface for selecting reports and filter-template combinations is chosen, the alerts contained in the report or filter and template combination may be listed in the display window of the interface.
In step 240, the schedule for the service is also selected. According to one embodiment, predefined schedules for voice services may be provided or a customized schedule for the voice service may be created. If a new schedule is to be created, a module may be opened to enable the schedule name and parameters to be set. Schedules may be run on a several-minute, hourly, daily, monthly, semi-annual, annual or other bases, depending upon what frequency is desired. According to one embodiment, an interface is provided that allows the administrator to browse through existing schedules and select an appropriate one. The interface may provide a browsing window for finding existing schedule files and a “new schedule” feature which initiates the schedule generating module. In one embodiment, schedules may not be set for alert type services. However, in some embodiments, a schedule for evaluating whether alert conditions have been met may be established in a similar manner.
In step 230, the duration of the service is also set. Service duration indicates the starting and stopping dates for the service. Setting a service duration may be appropriate regardless of whether a scheduled service or alert type service has been selected. The start date is the base line for the scheduled calculation, while the end date indicates when the voice service will no longer be sent. The service may start immediately or at some later time. According to one embodiment, the interface is provided to allow the administrator to input start and end dates. The interface may also allow the administrator to indicate that the service should start immediately or run indefinitely. Various calendar features may be provided to facilitate selection of start and stop dates. For example, a calendar that specifies a date with pull-down menus that allow selection of a day, month and year may be provided according to known methods of selecting dates in such programs as electronic calendar programs and scheduling programs used in other software products. One specific aid that may be provided is to provide a calendar with a red circle indicating the present date and a blue ellipse around the current numerical date in each subsequent month to more easily allow the user to identify monthly intervals. Other methods may also be used.
In step 220, a voice service may also be designated as a mid-tier slicing service. In one embodiment, mid-tier slicing services generate content and a dynamic subscriber list in a single query to an OLAP system. According to one embodiment, in a mid-tier slicing service a single database query is performed for all subscribers to the service. The result set developed by that query is organized in a table that contains a column that indicates one or more users that each row of data is applicable to.
In step 250, the content of the voice service is defined. Defining the content of the voice service may include selecting the speech to be delivered during the voice service broadcast (content), the structure of dialogs, menus, inputs, and the background procedures which generate both content and structure. In one embodiment, defining voice service content establishes the procedures performed by the vss server to assemble one or more active voice pages in response to initiation of the voice service. According to one embodiment, defining service content involves establishing a hierarchical structure of TML elements which define the structure and content of a voice service. All of the elements in a given service may be contained within a container.
The personalization type is selected in step 260. Personalization type defines the options that the administrator will have in applying personalization filters to a voice service. According to one embodiment, a personalization filter is a set of style properties that can be used to determine what content generated by the service will be delivered to the individual user and in what format it will be delivered. In one embodiment, personalizing the delivery format may include selection of style properties that determine the sex of the voice, the speed of the voice, the number of call back attempts, etc. Personalization filters may exist for individual users, groups of users, or types of users. According to one embodiment, personalization filters may be created independent of the voice service. According to this embodiment, a voice service specifies what filters are used when generating IVBs. Some personalization type options may include: allowing no personalization filters; allowing personalization filters for some users, but not requiring them; and requiring personalization filters for all interactive voice broadcasts made using the service.
According to one embodiment, specifying personalization type is accomplished by administrator input through an interface. The interface may offer a toggle list with the three options: required personalization, optional personalization, and no personalization.
The voice service may be stored in a database structure to enable users to retrieve predefined voice services and to subscribe to these services, for example, through subscription interfaces explained in conjunction
According to one embodiment, the method of
In one embodiment, setting error conditions may be accomplished using an error handling interface. The interface may allow the administrator to select either default error handling, or to customize error handling using a module for defining error handling. If default handling is selected, the system uses established settings. If customized handling is chosen, the user may use a feature to access the appropriate interface for the error handling module.
Servers may have limited capacity to perform all of the actions required of them simultaneously, the method of
In one embodiment, an interface is provided for defining the priority of the voice service being created or edited. According to one embodiment, the interface comprises a screen including option boxes with pull down menus listing the number of different prioritization options.
Another aspect of the invention relates to a method for executing a voice service.
According to one embodiment, content is created in step 310 as follows. A voice service execution begins by running scheduled reports, queries or by taking other action to determine whether the service should be sent. The subscribers for the service are then resolved. Datasets are generated for each group of subscribers that has unique personalization criteria.
Call structure may be created (step 320) as follows. An AVP contains data at various hierarchical content levels (nodes) that can be either static text or dynamic content. Static text can be generated e.g., by typing or by incorporating a text file. Dynamic content may be generated e.g., by inserting data from a data report using a grid an/or an XSL stylesheet. Moreover, content is not limited to text based information. Other media, such as, sound files, may be incorporated into the AVP. The call data (for example, at a particular level) may be the text that is converted to speech and played when the recipient encounters the node.
According to another embodiment, call content may include “standard” active voice pages that are generated and inserted into a database or Web Server where the pages are periodically refreshed. According to one particular embodiment, the active voice page that is generated for a user contains links to these standard active voice pages. The links may be followed using a process similar to web page links.
The call structure may comprise either a static structure that is defined in the voice service interfaces e.g., by typing text into a text box and/or a dynamic structure generated by grid/XSL combinations. The dynamic structure is merged with static structure during the service execution. A single call structure is created for each group of users that have identical personalization properties across all projects because such a group will receive the same content.
After a call structure is generated, in step 330, it is sent to a call database e.g., call database 1811 shown in
In step 340, a call request is processed. A call is implemented on call server 18 using one of several ports that are configured to handle telephone communication. When a port becomes available, the call request is removed from the queue and the call is made to the user. As the user navigates through an active voice page, e.g., by entering input using the key pad or by speaking responses, call/content is presented by converting text to speech in text-to-speech engine 1814. User input during the call may be stored for processing. According to another embodiment, user responses and other input may also be used to follow links to other active voice pages. For example, as explained above, “standard” active voice pages may be generated and inserted into a database or Web Server. Then, when a user's voice service is delivered, that voice service may contain links to information that may be accessed by a user. A user may access those standard active voice pages by entering input in response to OPTION or PROMPT elements.
In step 350, user responses are stored by the system. According to one embodiment, user responses are stored in a response collection defined by the active voice page. A voice service may specify that a subscriber return information during an IVB so that another application may process the data. For instance, a user may be prompted to purchase a commodity and be asked to enter or speak the number of units for the transaction. During or after an IVB, the subscriber's responses are written to a location from which they can be retrieved for processing (e.g., by an external application).
a depicts an embodiment of a system according to one embodiment of the present invention. Preferably, the system comprises database system 12, a DSS server 14, voice server 16, a call server 18, subscription interface 20, and other out input/files 24.
Database system 12 and DSS server 14 comprise an OLAP system that generates user-specified reports from data maintained by database system 12. Database system 12 may comprise any data warehouse or data mart as is known in the art, including a relational database management system (“RDBMS”), a multidimensional database management system (“MDDBMS”) or a hybrid system. DSS server 14 may comprise an OLAP server system for accessing and managing data stored in database system 12. DSS server 14 may comprise a ROLAP engine, MOLAP engine or a HOLAP engine according to different embodiments. Specifically, DSS server 14 may comprise a multithreaded server for performing analysis directly against database system 12. According to one embodiment, DSS server 14 comprises a ROLAP engine known as DSS Server™ offered by MicroStrategy.
Voice service server (VSS) 16, call server 18 and subscription interface 20 comprise a system through which subscribers request data and reports e.g., OLAP reports through a variety of ways and are verbally provided with their results through an IVB. During an IVB, subscribers receive their requested information and may make follow-up requests and receive responses in real-time as described above. Although the system is shown, and will be explained, as being comprised of separate components and modules, it should be understood that the components and modules may be combined or further separated. Various functions and features may be combined or separated
Subscription interface 20 enables users or administrators of the system to monitor and update subscriptions to various services provided through VSS 16. Subscription interface 20 includes a world wide web (WWW) interface 201, a telephone interface 202, other interfaces as desired and a subscriber API 203. WWW interface 201 and telephone interface 202 enable system 100 to be accessed, for example, to subscribe to voice services or to modify existing voice services. Other interfaces may be used. Subscriber API 203 provides communication between subscription interface 20 and VSS 16 so that information entered through subscription interface 20 is passed through to VSS 16.
Subscription interface 20 is also used to create a subscriber list by adding one or more subscribers to a service. Users or system administrators having access to VSS 16 may add multiple types of subscribers to a service such as a subscriber from either a static recipient list (SRL) (e.g., addresses and groups) or a dynamic recipient list (DRL) (described in further detail below). The subscribers may be identified, for example, individually, in groups, or as dynamic subscribers in a DRL. Subscription interface 20 permits a user to specify particular criteria (e.g., filters, metrics, etc.) by accessing database system 12 and providing the user with a list of available filters, metrics, etc. The user may then select the criteria desired to be used for the service. Metadata may be used to increase the efficiency of the system.
A SRL is a list of manually entered names of subscribers of a particular service. The list may be entered using subscription interface 20 or administrator console 161. SRL entries may be personalized such that for any service, a personalization filter (other than a default filter) may be specified. A SRL enables different personalizations to apply for a login alias as well. For example, a login alias may be created using personalization engine 1632. Personalization engine 1632 enables subscribers to set preferred formats, arrangements, etc. for receiving content. The login alias may be used to determine a subscriber's preferences and generate service content according to the subscriber's preferences when generating service content for a particular subscriber.
A DRL may be a report which returns lists of valid user names based on predetermined criteria that are applied to the contents of a database such as database system 12. Providing a DRL as a report enables the DRL to incorporate any filtering criteria desired, thereby allowing a list of subscribers to be derived by an application of a filter to the data in database system 12. In this manner, subscribers of a service may be altered simply by changing the filter criteria so that different user names are returned for the DRL. Similarly, subscription lists may be changed by manipulating the filter without requiring interaction with administrator console 161. Additionally, categorization of each subscriber may be performed in numerous ways. For example, subscribers may be grouped via agent filters. In one specific embodiment, a DRL is created using DSS Agent™ offered by Micro Strategy.
VSS 16 is shown in more detail in
System administrator module 1611 comprises a number of interfaces that enable selection and control of the parameters of system 100. For example, system administrator module 1611 enables an administrator to specify and/or modify an email system, supporting servers and a repository server with which system 100 is to be used. System administrator 1611 also enables overall control of system 100. For example, system administrator module is also used to control the installation process and to start, stop or idle system 100. According to one embodiment, system administrator 1611 comprises one or more graphical user interfaces (GUIs).
Scheduling module 1612 comprises a number of interfaces that enable scheduling of voice services. Voice services may be scheduled according to any suitable methodology, such as according to scheduled times or when a predetermined condition is met. For example, the predetermined condition may be a scheduled event (time-based) including, day, date and/or time, or if certain conditions are met. In any event, when a predetermined condition is met for a given service, system 100 automatically initiates a call to the subscribers of that service. According to one embodiment, scheduling module 1612 comprises one or more GUIs.
Exceptions module 1613 comprises one or more interfaces that enable the system administrator to define one or more exceptions, triggers or other conditions. According to one embodiment, exceptions module 1613 comprises one or more GUIs.
Call settings module 1614 comprises one or more interfaces that enable the system administrator to select a set of style properties for a particular user or group of users. Each particular user may have different options for delivery of voice services depending on the hardware over which their voice services are to be delivered and depending on their own preferences. As an example of how the delivery of voice services depends on a user's hardware, the system may deliver voice services differently depending on whether the user's terminal device has voice mail or not. As an example of how the delivery of voice services depends on a user's preferences, a user may chose to have the pitch of the voice, the speed of the voice or the sex of the voice varied depending on their personal preferences. According to one embodiment, call settings module 1614 comprises one or more GUIs.
Address handling module 1615 comprises one or more interface that enable a system administrator to control the address (e.g., the telephone number) where voice services content is to be delivered. The may be set by the system administrator using address handling module 1615. According to one embodiment, address handling module 1615 comprises one or more GUIs.
Voice service wizard module 1616 comprises a collection of interfaces that enable a system administrator to create and/or modify voice services. According to one embodiment, service wizard module 1616 comprises a collection of interfaces that enable a system administrator to define a series of dialogs that contain messages and inputs and determine the call flow between these dialogs based on selections made by the user. The arrangement of the messages and prompts and the flow between them comprises the structure of a voice service. The substance of the messages and prompts is the content of a voice service. The structure and content are defined using service wizard module 1616.
Voice service API 162 (e.g., MicroStrategy Telecaster Server API) provides communication between administrator console 161 and backend server 163. Voice Service API 162 thus enables information entered through administrator console 161 to be accessed by backend server 163 (e.g., MicroStrategy Telecaster Server).
Backend server 163 utilizes the information input through administrator console 161 to initiate and construct voice services for delivery to a user. Backend server 163 comprises report formatter 1631, personalization engine 1632, scheduler 1633 and SQL engine 1634. According to one embodiment, backend server 163 comprises MicroStrategy Broadcast Server. Report formatter 1631, personalization engine 1632, and scheduler 1633 operate together, utilizing the parameters entered through administrator console 161, to initiate and assemble voice services for transmission through call server 18. Specifically, scheduler 1633 monitors the voice service schedules and initiates voice services at the appropriate time. Personalization engine 1632 and report formatter 1631 use information entered through service wizard 1616, exceptions module 1613, call settings module 1614, and address module 1615, and output provided by DSS server 14 to assemble and address personalized reports that can be sent to call server 18 for transmission. According to one embodiment, report formatter 1631 includes an XML based markup language engine to assemble the voice services. In a particular embodiment, report formatter includes a Telecaster Markup Language engine offered by MicroStrategy Inc. to assemble the call content and structure for call server 18.
SQL engine 1634 is used to make queries against a database when generating reports. More specifically, SQL engine 1634 converts requests for information into SQL statements to query a database.
Repository 164 may be a group of relational tables stored in a database. Repository 164 stores objects which are needed by system 100 to function correctly. More than one repository can exist, but preferably the system 100 is connected to only one repository at a time.
According to one embodiment, a call server 18 is used to accomplish transmission of the voice services over standard telephone lines. Call server 18 is shown in more detail in
Call database 1811 comprises storage for voice services that have been assembled in VSS 16 and are awaiting transmission by call server 18. These voice services may include those awaiting an initial attempt at transmission and those that were unsuccessfully transmitted (e.g., because of a busy signal) and are awaiting re-transmission. According to one embodiment, call database 1811 comprises any type of relational database having the size sufficient to store an outgoing voice service queue depending on the application. Call database 1811 also comprises storage space for a log of calls that have been completed.
Voice services stored in call database 1811 are preferably stored in a mark-up language. Mark-up language parsing engine 1812 accepts these stored voice services and separates the voice services into parts. That is, the mark-up language version of these voice services comprises call content elements, call structure elements and mark-up language instructions. Mark-up language parsing engine 1812 extracts the content and structure from the mark-up language and passes them to call builder 1813.
Call builder 1813 is the module that initiates and conducts the telephone call to a user. More specifically, call builder dials and establishes a connection with a user and passes user input through to markup language parsing engine 1812. In one embodiment, call builder 1813 comprises “Call Builder” software available from Call Technologies Inc. Call builder 1813 may be used for device detection, line monitoring for user input, call session management, potentially transfer of call to another line, termination of a call, and other functions.
Text-to-speech engine 1814 works in conjunction with mark-up language parsing engine 1812 and call builder 1813 to provide verbal communication with a user. Specifically, after call builder 1813 establishes a connection with a user, text-to-speech engine 1814 dynamically converts the content from mark-up language parsing engine 1812 to speech in real time.
A voice recognition module may be used to provide voice recognition functionality for call server 181. Voice recognition functionality may be used to identify the user at the beginning of a call to help ensure that voice services are not presented to an unauthorized user or to identify if a human or machine answers the call. This module may be a part of call builder 1813. This module may also be used to recognize spoken input (say “one” instead of press “1”), enhanced command execution (user could say “transfer money from my checking to savings”), enhanced filtering (instead of typing stock symbols, a user would say “MSTR”), enhanced prompting, (saying numeral values).
User response module 1815 comprises a module that stores user responses and passes them back to intelligence server 16. Preferably, this is done within an AVP. During a telephone call, a user may be prompted to make choices in response to prompts by the system. Depending on the nature of the call, these responses may comprise, for example, instructions to buy or sell stock, to replenish inventory, or to buy or rebook an airline flight. User response module 1815 comprises a database to store these responses along with an identification of the call in which they were given. The identification of the call in which they were given is important to determining what should be done with these responses after the call is terminated. User responses may be passed back to intelligence server 16 after the call is complete. The responses may be processed during or after the call, by the system or by being passed to another application.
Statistics accumulator 1816 comprises a module that accumulates statistics regarding calls placed by call builder 1813. These statistics including, for example, the number of times a particular call has been attempted, the number of times a particular call has resulted in voice mail, the number of times a user responds to a call and other statistics, can be used to modify future call attempts to a particular user or the structure of a voice service provided to a particular user. For example, according to one embodiment, statistics accumulator 1816 accumulates the number of times a call has been unsuccessfully attempted by call builder 1813. This type of information is then used by call server 18 to determine whether or not the call should be attempted again, and whether or not a voice mail should be left. 1822 preferably comprises voice boards available from Dialogic, Inc. Other processors and voice synthesizers meeting system requirements may be used.
The system and method of the present invention may form an integral part of an overall commercial transaction processing system.
According to one embodiment of the present invention, a system and method that enable closed-loop transaction processing are provided. The method begins with the deployment of an IVB by executing a service. As detailed above, this includes generating the content and combining this with personalization information to create an active voice page. Call server 18 places a call to the user. During the call, information is delivered to the user through a voice-enabled terminal device (e.g., a telephone or cellular phone). Phone lines 183 may be used for communication purposes.
During the IVB, a user may request a transaction, service, further information from the database or other request, e.g., based on options presented to the user. These will generically be referred to as transactions. The request may be, but is not necessarily, based on or related to information that was delivered to the user. According to one embodiment, the request comprises a user response to a set of options and/or input of information through a telephone keypad, voice input or other input mechanism. According to another embodiment, the request can be made by a user by speaking the request. Other types of requests are possible.
According to one embodiment, the user responses are written to a response collection, which along with information stored in the active voice page, can be used to cause a selected transaction to be executed. According to one embodiment, the active voice page comprises an XML-based document that includes embedded, generic requests, e.g., a request for a transaction, or a request for additional information (a database query). These embedded requests are linked with, for example option statements or prompts so that when a user enters information, the information is entered into the generic request and thus completes a specific transaction request. For example, in the example if a user exercises an option to buy a particular stock, that stock's ticker symbol is used to complete a generic “stock buy” that was embedded in the active voice page.
According to one embodiment, tokens are used to manage user inputs during the IVB. A token is a temporary variable that can hold different values during an IVB. When a user enters input, it is stored as a token. The token value is used to complete a transaction request as described above. According to one embodiment, the system maintains a running list of tokens, or a response collection, during an IVB.
In order to complete the requested transaction, the user responses (and other information from the active voice page) may need to be converted to a particular format. The format will depend, for example, on the nature and type of transaction requested and the system or application that will execute the transaction. For example, a request to purchase goods through a web-site may require the information to be in HTML/HTTP format. A request for additional information may require and SQL statement. A telephone-based transaction may require another format.
Therefore, the transaction request is formatted. According to one embodiment, the transaction is formatted to be made against a web-based transaction system. According to another embodiment, the transaction request is formatted to be made against a database. According to another embodiment, the transaction is formatted to be made against a telephone-based transaction system. According to another embodiment, the transaction is formatted to be made via e-mail or EDI. Other embodiments are possible.
In one embodiment, the formatted transaction request comprises an embedded transaction request. The system described in connection with
For example, in connection with an exemplary stock purchase, an active voice page can include an embedded transaction request to sell stock in the format necessary for a particular preferred brokerage. The embedded statement would include predefined variables for the name of the stock, the number of shares, the type of order (market or limit, etc.), and other variables. When the user chooses to exercise the option to buy or sell stock, the predefined variables are replaced with information entered by the user in response to OPTION or PROMPT elements. Thus, a properly formatted transaction request is completed.
In the system of
According to another embodiment, where the transaction request is made via a natural language, voice request, a formatted transaction request can be generated in a number of ways. According to one embodiment, speech recognition technology is used to translate the user's request into text and parse out the response information. The text is then used to complete an embedded transaction request as described above. According to another embodiment, speech recognition software is used to translate the request to text. The text is then converted to a formatted request based on a set of known preferences.
A connection is established with the transaction processing system. This can be accomplished during, or after the IVB. According to one embodiment, the transaction processing system comprises a remotely located telephone-based transaction site. For example, in the system shown in
According to another embodiment, the transaction processing system comprises a remotely based web-site. According to this embodiment, the formatted request includes a URL to locate the web-site and the system accesses the site through a web connection using the formatted request. Alternatively, the formatted request includes an e-mail address and the system uses any known email program to generate an e-mail request for the transaction.
After the connection is established, the transaction is processed by the transaction processing site and the user is notified of the status of the transaction. If the transaction is completed in real-time, the user may be immediately notified. If the transaction is executed after the IVB, the user may be called again by the system, sent an e-mail, or otherwise notified when the transaction has been completed.
According to one particular embodiment, the system comprises the interactive voice broadcasting system shown and described in
A voice service system 415 is provided to enable access to the information in the databases. The voice service system utilizes personalization information 420 and personalized menus 425 to construct AVPs 430 pages that enable the information to be delivered to a user verbally. Moreover, the AVPs pages not only enable information to be presented to the user, but they also enable the user to provide information back to the voice service system for additional processing.
According to the embodiment shown in
During the IVB, depending on the content that is being delivered, control may be passed to an e-commerce application 465 for the user to complete a transaction based on the information presented. For example, if the user has requested information about sales on a particular brand of merchandise, the user may be connected with a particular retailer in order to complete a transaction to buy a particular good or service. Information about this transaction is then added to the databases and thus may be advantageously accessed by other users.
It may not be economical for some potential users of a voice broadcasting system to buy and/or maintain their own telephony hardware and software as embodied in call server 18. In such a case, a voice service bureau may be maintained at a remote location to service users voice service requests. A voice service bureau and a method of using a voice service bureau according to various embodiments of the present invention is described in conjunction with
In one embodiment, a voice service bureau may comprise one or more call servers and call databases that are centrally located and enable other voice service systems to generate a call request and pass the call request to the VSB to execute a call. In this way the other voice service systems do not need to invest in acquiring and maintaining call data bases, call servers, additional telephone lines and other equipment or software. Moreover, the VSB facilitates weeding out usage of illegal numbers and spamming by number checking implemented through its web server.
A voice service bureau and a method of using a voice service bureau according to one embodiment are described in conjunction with
According to one embodiment, the voice service bureau is maintained at a location distant from the voice service system. Therefore, in order for a voice service to be processed by the voice service bureau, in step 810 the voice service is sent to the voice services bureau, preferably over some secure line of communication. According to one embodiment, the request is sent to the voice service bureau through the Internet using secure HTTPS. HTTPS provides a secure exchange of data between clients and the voice service bureau using asymmetric encryption keys based on secure server certificates. In another embodiment, SSL HTTP protocol is used to send a call request to the voice service bureau. Both of these protocols help ensure that a secure channel of communication is maintained between the voice service system and the voice service bureau. Other security techniques may be used.
When a request for a call or telecast is received, by the VSB, the request is authenticated by the voice service bureau in step 820. According to one embodiment, the authenticity of the request is determined in at least two ways. First, it is determined whether or not the request was submitted from a server having a valid, active server certificate. More specifically, requests may be typically received via a stream of HTTPS data. Each such request originating from a server with a valid server certificate will include an embedded code (i.e., server certificate) that indicates the request is authentic. In addition to the use of server certificates, each request may also be authenticated using an identification number and password. Therefore, if the request submitted does not include a valid server certificate and does not identify a valid I.D./password combination, the request will not be processed. The step of authenticating also comprises performing any necessary decryption. According to one embodiment, any errors that are encountered in the process of decrypting or authenticating the call request are logged an error system and may be sent back to the administrator of the sending system. Other methods of authenticating the request are possible.
Each properly authenticated request is sent to a call server (step 830) and processed (step 840). According to one embodiment, the voice service bureau comprises a number of call servers. According to one embodiment, the calls are sent to a call database, and processed as set forth herein in conjunction with the explanation of call server 18.
One embodiment of a voice service bureau will now be explained in conjunction with
According to one embodiment, client side installations 91 are substantially identical to the system shown in
According to this embodiment, when voice services have been assembled by intelligence server 16, a request to have the voice services transmitted is sent via a secure network connection through the computer network shown to primary voice bureau 92 and backup voice service bureau 94 as described above. According to one embodiment, the request comprises a mark-up language string that contains the voice service structure and content and personal style properties and other information. As described above, voice bureau 92 authenticates the request, queues the voice services and sends telecasts to users 95 through the voice network.
A block diagram of one embodiment of primary voice bureau 92 is shown in
Dual-homed servers 922 comprise servers configured to receive and send HTTPS email. As part of their receiving function, dual-homed servers 922 are configured to perform the authentication processing described above. According to one embodiment, dual-homed servers 922 determine whether the incoming request originated from a server with an active server certificate and also determine if the request contains a valid I.D./password combination. Once dual-homed servers 922 have authenticated the incoming request, they forward the request to be queued in call database 924. As part of their sending function, dual-homed servers 922 are configured to format and send HTTPS email. As discussed above, during a telecast a user may request that further information be accessed from a database or that some transaction be performed. According to one embodiment, these user requests are forwarded back to the originating system via HTTPS email by dual-homed servers 922. Dual-homed servers 922 are load balanced to facilitate optimal performance and handling of incoming call requests.
Database servers 923, call database 924, and backup storage 925 together comprise a call request queuing system. Primary voice bureau 92 is configured to handle a large number of call requests. It may not be possible to process call requests as they arrive. Therefore, call requests are queued in call database 924. According to one embodiment, call database 924 comprises a relational database that maintains a queue of all call requests that need to be processed as well as logs of calls that have been processed. According to another embodiment, primary VSB 92 may include a failover measure that enables another system server to become the call database if call database 924 should fail.
Database servers 923 are configured to control access to call database 924. According to one embodiment, database servers may be optimized to generate SQL statements to access entries in call database at high speed. Database servers 923 also control storage of call requests and call logs in call database 924.
Call servers 926 each are configured to format and send telecasts. According to one embodiment, each of call servers 926 is substantially identical to call server 18 shown in
Primary voice bureau 92 is controlled by system administrator 93 and internal switch 927. System administrator controls switch 927 and thus controls the flow of call requests to call database 924 from dual homed servers 922 and to call servers 926 from call database 924.
System administrator 93 is also configured to perform a number of other services for primary voice bureau 92. According to one embodiment, system administrator 93 also comprises a billing module, a statistics module, a service module and a security module. The billing modules tabulates the number of voice service requests that come from a particular user and considers the billing plan that the customer uses so that the user may be appropriately billed for the use of voice bureau 92. The statistics module determines and maintains statistics about the number of call requests that are processed by voice bureau 92 and statistics regarding call completion such as, e.g., success, failed due to busy signal and failed due to invalid number. These statistics may be used, for example, to evaluate hardware requirements and modify pricing schemes. The security module monitors activity on voice bureau 92 to determine whether or not any unauthorized user has accessed or attempted to access the system. The service module provides an interface through which primary voice bureau 92 may be monitored, for example, to determine the status of call requests. Other service modules are possible. Moreover, although these services are described as distinct modules, their functionality could be combined and provided in a single module.
Backup voice service bureau 94 receives a redundant request for voice services. Backup voice service bureau 94 processes the requests only when primary voice service bureau is offline or busy. One embodiment of backup voice service bureau 94 is shown in
The systems and methods discussed above are directed to outbound broadcasting of voice services. Nevertheless, in certain situations, for example when the out bound telecast is missed, it is desirable to for a voice service system to enable inbound calling. According to another embodiment, a method and system for providing integrated inbound and outbound voice services is disclosed.
A method for providing inbound access to voice services according to one embodiment of the present invention is shown in
In step 1230, a voice page is located. As explained above, a telecast of a voice service is driven by an active voice page. Accordingly, a user calling in to access voice services locates the desired active voice page. According to one embodiment, the user is automatically placed into an active voice page of a voice service that the user missed. That is, the system chooses an active voice page that it was unable to deliver. According to this embodiment, when a call is undeliverable (e.g., when an answering machine picks up), the active voice page for that call is placed in memory in a “voice site” table or as an active voice page on a web site and addressed using the user's identification. When the user calls in to retrieve the voice service, after the user logs in, the table or web site will be searched for an active voice page that corresponds to their identification. If such a page exists, it is executed by the call server.
Other possibilities exist for accessing active voice pages through inbound calling. According to another embodiment, the system maintains a log of all voice services sent and provides an inbound user an option to select one of their previous voice services. According to another embodiment, an inbound caller is automatically placed into an active voice page that presents the user with an option to select one of that user's most frequently used services. According to still another embodiment, the user is allowed to search for past active voice pages by date or content. For example, the user may be prompted to enter a date on or near which the desired voice page was executed. According to another embodiment, the user may use the telephone keys to enter a search term and search the content of any previously executed active voice page that they are authorized to access or that is not secure.
Once an active voice page is located, the user navigates through the active voice page in step 1240. As described above, a user navigates through an active voice by exercising options, responding to prompts and otherwise entering input to the system. An inbound calling system would thus have access to the full functionality of the voice service system described in conjunction with
In order to receive inbound calls, call server 18a comprises call receiver module 1817. Although, call server 18 discussed above contains hardware permitting reception of calls as well as transmission of calls, it is not set up to receive calls. Call receiver module 1817 enables call server 18a to receive calls and routes the incoming calls to security module 1818. According to one embodiment, call receiver module comprises a software component designed to configure call server 18a to receive calls. Other embodiments are possible.
Received calls are forwarded to security module 1818 for authentication. According to one embodiment discussed above, incoming calls are authenticated using login I.D.'s and passwords. According to another embodiment, automatic number identification software is used to identify and authenticate callers. According to another embodiment, speech recognition and pattern matching techniques are used to identify a caller.
Authenticated calls may search for an active voice page using search module 1819. According to one embodiment, search module 1819 comprises a search engine designed specifically to search active voice pages. According to one embodiment discussed above, active voice pages utilize an XML-based language and search module 1819 comprises an XML-based search engine. According to another embodiment, search module 1819 comprises a SQL engine designed to make queries against a relational or other type of database.
The active voice pages that are being search are stored in enhanced call database 1811a. In addition to its facilities to queue and log calls, enhanced call database 1811 includes facilities to catalog active voice pages. According to one embodiment, enhanced call database comprises a relational or other type of database. According to this embodiment, enhanced call database is used to store and categorize active voice pages and corresponding parameters, such as expiration dates for active voice pages. Other storage facilities are possible.
