The features, functions, and advantages that have been discussed may be achieved independently in various embodiments of the present invention or may be combined with yet other embodiments, further details of which can be seen with reference to the following description and drawings.
Having thus described embodiments of the invention in general terms, reference will now be made the accompanying drawings, wherein:
Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Where possible, any terms expressed in the singular form herein are meant to also include the plural form and vice versa, unless explicitly stated otherwise. Also, as used herein, the term “a” and/or “an” shall mean “one or more,” even though the phrase “one or more” is also used herein. Furthermore, when it is said herein that something is “based on” something else, it may be based on one or more other things as well. In other words, unless expressly indicated otherwise, as used herein “based on” means “based at least in part on” or “based at least partially on.” Like numbers refer to like elements throughout.
As described herein, the term “entity” may be any organization that develops, provides, utilizes, tests, and/or deploys an Interactive Voice Response platform/system to one or more end users (e.g., customers, potential customers, employees, contractors, and/or the like) of the entity. In some embodiments, the entity may be a financial institution which may include herein may include any financial institutions such as commercial banks, thrifts, federal and state savings banks, savings and loan associations, credit unions, investment companies, insurance companies and the like. In some embodiments, the entity may be a non-financial institution.
Many of the example embodiments and implementations described herein contemplate interactions engaged in by a user with a computing device and/or one or more communication devices and/or secondary communication devices. A “user”, as referenced herein, may refer to an entity or individual that has the ability and/or authorization to access and use one or more applications, systems, servers, and/or devices provided by the entity and/or the system of the present invention. Furthermore, as used herein, the term “user computing device” or “mobile device” may refer to mobile phones, computing devices, tablet computers, wearable devices, smart devices and/or any portable electronic device capable of receiving and/or storing data therein.
A “user interface” is any device or software that allows a user to input information, such as commands or data, into a device, or that allows the device to output information to the user. For example, the user interface includes a graphical user interface (GUI) or an interface to input computer-executable instructions that direct a processing device to carry out specific functions. The user interface typically employs certain input and output devices to input data received from a user or to output data to a user. These input and output devices may include a display, mouse, keyboard, button, touchpad, touch screen, microphone, speaker, LED, light, joystick, switch, buzzer, bell, and/or other user input/output device for communicating with one or more users.
Interactive Voice Response (IVR) platforms may be provided by an entity to one or more end users (e.g., customers, potential customers, employees, or the like). IVR platforms are automated systems that provide information to incoming callers. Such IVR platforms may be developed by an entity and during the development, testing, and deployment phases of the IVR platform, users (e.g., application developers, application testers, application designer, or the like) may face difficulty to test functionalities of the IVR platform that are being developed/tested/deployed. Users typically have to call the IVR system to test every single functionality, complete the call, and then wait for the voice log to be generated before initiating the process of debugging. After performing debugging and potentially fixing the functionality, the user has to restart the IVR platform server and start the testing process all over again, thereby reducing the overall efficiency of the process and increasing consumption of processing power of IVR servers for multiple voice log generation and restart of the IVR platform server. As such, there exists a need for system to overcome these difficulties and provide a solution for converting real-time voice logs to user interface logs for debugging of Interactive Voice Response (IVR) interactions in real-time.

Some embodiments of the computing device system 400 include a processor 410 communicably coupled to such devices as a memory 420, user output devices 436, user input devices 440, a network interface 460, a power source 415, a clock or other timer 450, a camera 480, and a positioning system device 475. The processor 410, and other processors described herein, generally include circuitry for implementing communication and/or logic functions of the computing device system 400. For example, the processor 410 may include a digital signal processor device, a microprocessor device, and various analog to digital converters, digital to analog converters, and/or other support circuits. Control and signal processing functions of the computing device system 400 are allocated between these devices according to their respective capabilities. The processor 410 thus may also include the functionality to encode and interleave messages and data prior to modulation and transmission. The processor 410 can additionally include an internal data modem. Further, the processor 410 may include functionality to operate one or more software programs, which may be stored in the memory 420. For example, the processor 410 may be capable of operating a connectivity program, such as a web browser application 422. The web browser application 422 may then allow the computing device system 400 to transmit and receive web content, such as, for example, location-based content and/or other web page content, according to a Wireless Application Protocol (WAP), Hypertext Transfer Protocol (HTTP), and/or the like.
The processor 410 is configured to use the network interface 460 to communicate with one or more other devices on the network 150. In this regard, the network interface 460 includes an antenna 476 operatively coupled to a transmitter 474 and a receiver 472 (together a “transceiver”). The processor 410 is configured to provide signals to and receive signals from the transmitter 474 and receiver 472, respectively. The signals may include signaling information in accordance with the air interface standard of the applicable cellular system of the wireless network 150. In this regard, the computing device system 400 may be configured to operate with one or more air interface standards, communication protocols, modulation types, and access types. By way of illustration, the computing device system 400 may be configured to operate in accordance with any of a number of first, second, third, and/or fourth-generation communication protocols and/or the like.

The computing device system 400 may also be configured to operate in accordance with non-cellular communication mechanisms, such as via a wireless local area network (WLAN) or other communication/data networks.
As described above, the computing device system 400 has a user interface that is, like other user interfaces described herein, made up of user output devices 436 and/or user input devices 440. The user output devices 436 include a display 430 (e.g., a liquid crystal display or the like) and a speaker 432 or other audio device, which are operatively coupled to the processor 410.
The user input devices 440, which allow the computing device system 400 to receive data from a user such as the user 110 may include any of a number of devices allowing the computing device system 400 to receive data from the user 110, such as a keypad, keyboard, touch-screen, touchpad, microphone, mouse, joystick, other pointer device, button, soft key, and/or other input device(s). The user interface may also include a camera 480, such as a digital camera.
The computing device system 400 may also include a positioning system device 475 that is configured to be used by a positioning system to determine a location of the computing device system 400. For example, the positioning system device 475 may include a GPS transceiver. In some embodiments, the positioning system device 475 is at least partially made up of the antenna 476, transmitter 474, and receiver 472 described above. For example, in one embodiment, triangulation of cellular signals may be used to identify the approximate or exact geographical location of the computing device system 400. In other embodiments, the positioning system device 475 includes a proximity sensor or transmitter, such as an RFID tag, that can sense or be sensed by devices known to be located proximate a merchant or other location to determine that the computing device system 400 is located proximate these known devices.
The computing device system 400 further includes a power source 415, such as a battery, for powering various circuits and other devices that are used to operate the computing device system 400. Embodiments of the computing device system 400 may also include a clock or other timer 450 configured to determine and, in some cases, communicate actual or relative time to the processor 410 or one or more other devices.
The computing device system 400 also includes a memory 420 operatively coupled to the processor 410. As used herein, memory includes any computer readable medium (as defined herein below) configured to store data, code, or other information. The memory 420 may include volatile memory, such as volatile Random Access Memory (RAM) including a cache area for the temporary storage of data. The memory 420 may also include non-volatile memory, which can be embedded and/or may be removable. The non-volatile memory can additionally or alternatively include an electrically erasable programmable read-only memory (EEPROM), flash memory or the like.
The memory 420 can store any of a number of applications which comprise computer-executable instructions/code executed by the processor 410 to implement the functions of the computing device system 400 and/or one or more of the process/method steps described herein. For example, the memory 420 may include such applications as a conventional web browser application 422, a real-time voice log conversion application 421, an entity application 424, or the like. These applications also typically instructions to a graphical user interface (GUI) on the display 430 that allows the user 110 to interact with the entity system 200, the real-time voice log conversion system 300, and/or other devices or systems. The memory 420 of the computing device system 400 may comprise a Short Message Service (SMS) application 423 configured to send, receive, and store data, information, communications, alerts, and the like via the wireless network 150.
The memory 420 can also store any of a number of pieces of information, and data, used by the computing device system 400 and the applications and devices that make up the computing device system 400 or are in communication with the computing device system 400 to implement the functions of the computing device system 400 and/or the other systems described herein.
In one embodiment, a developer may access the voice interaction processing platform, via a user device (e.g., computing device system 400) and may initiate a voice flow associated with a functionality provided by the voice interaction processing platform. For example, the voice interaction processing platform may be associated with a financial institution and the developer developing a payment information functionality associated with the voice interaction processing platform may initiate an interaction to initiate a voice flow associated with the payment information functionality to debug the code associated with the payment information functionality.
As shown in block 510, the system generates a real-time voice log associated with the real-time voice interaction. The real-time voice log may be a Voice Extensible Markup Language (VXML) log file, where the real-time voice log comprises voice interactions between the user and the voice interaction processing platform. In some embodiments, the real-time voice log may comprise other information including, but not limited to, type of channel to initiate the interaction, user information, unique identification information (e.g., Social Security Number, username, account number, employee ID number, password, access codes, or the like), user device information associated with the user device used to initiate the interaction, inputs provided by the user during the interaction, timestamps associated with the inputs, application server, IVR server information, caller ID, and/or the like. In some embodiments, where the user provides unique identification information (e.g., Social Security Number, or the like) or any other confidential information or sensitive information, the system identifies such information and masks the unique identification information, confidential information, sensitive information, and/or the like. In some embodiments, masking of information may be based on a role associated with the user. The system identifies the role associated with the user, determines a type of the role, and performs masking based on the type of the role. For example, the system may mask personal information for all users. In another example, the system may mask access codes for testers and designers. In some embodiments, the system may also identify availability of data for the user based on the type of the role for user.
As shown in block 515, the system parses the real-time voice log, via real-time parser. Parsing the real-time voice log comprises reading and/or processing the Voice Extensible Markup Language log file generated by the system in block 510. The system may parse the real-time voice log based on the type of the role associated with the user. For example, the system may parse only a first set of information, a second set of information, and a third set of information from the real-time voice log instead of processing the entire real-time voice log based on the role of the user testing a functionality associated with the voice interaction processing platform.
As shown in block 520, the system converts, in real-time via a real-time converter, the parsed voice log to a real-time user interface log. Converting the parsed voice log to a user interface log comprises identifying at least one or more segments activated during the voice flow, utterances of the user, language information, prompts provided during the IVR response to the user, and/or the like. The system generates a user interface log displaying at least the one or more segments activated during the voice flow, the utterances provided by the user, the language information, the prompts provided during the IVR response to the user, and/or the like. In some embodiments, the one or more segments are displayed in the form of program code. In some embodiments, the one or more segments are displayed in the form of user interface (UI) elements that represent the voice flow based on the inputs provided by the user. In some embodiments, the one or more segments are displayed in the form of a table.
As shown in block 525, the system generates a real-time user interface comprising the real-time user interface log. In some embodiments, the system may also display the other information captured by the system including, but not limited to, type of channel to initiate the interaction, user information, user device information associated with the user device used to initiate the interaction, inputs provided by the user during the interaction, timestamps associated with the inputs, and/or the like. An example of the real-time user interface generated by the system is shown in
As shown in block 530, the system displays the real-time user interface comprising the real-time user interface log to the user for debugging the real-time voice interaction. In some embodiments, the system may display a modified real-time user interface to each user viewing the real-time user interface for debugging the real-time voice interaction. In some embodiments, the system identifies the role associated with the user, determines the type of the role, and generates the real-time user interface based on the type of the role associated with the user. For example, the system may determine, based on the unique user identification information provided by the user during the real-time voice interaction, that the user is an application developer, and may instantaneously modify the real-time user interface to create a custom user interface for application developers, wherein information displayed on the real-time user interface may comprise server ID, application server, IVR server information, version, logger statements call ID, Dialogue nodes, session ID, runtime errors, and/or the like. In another example, the system may determine, based on the unique user identification information provided by the user during the real-time voice interaction, that the user is an application designer, and may instantaneously modify the real-time user interface to create a custom user interface for application designers, wherein information displayed on the real-time user interface may comprise dialogue nodes, utterance ID, utterance, server name, call ID, language details, and/or the like. For example, the system may determine, based on the unique user identification information provided by the user during the real-time voice interaction, that the user is an application tester, and may instantaneously modify the real-time user interface to create a custom user interface for application testers, wherein information displayed on the real-time user interface may comprise call ID, call nodes, logging statements, prompts wording, dialogue nodes, application errors, and/or the like. In some embodiments, the system may generate a real-time utterance transcription associated with the real-time voice interaction and display the real-time utterance transcription in the real-time user interface.
In some embodiments, the system comprises an artificial intelligence engine that analyzes the real-time user interface log and the real-time voice logs and debugs the voice flow associated with the real-time voice interaction to identify one or more errors. Upon identification of the errors, the system may generate one or more remediation steps and/or recommendations to fix the errors or to improve the voice flow associated with the real-time voice interaction as shown in block 535. For example, if the user initiated a voice flow associated with payment information and the platform provided IVR response associated with account balance, the system identifies such a response as an error, via an artificial intelligence engine, and provides a remediation step to automatically correct the program code by replacing account balance IVR response linked with the payment information tag with a payment information IVR response. It should be understood that the examples provided herein are for explanatory purposes only and do not delineate the scope of the invention. As such, the process flow described herein may be applied to any non-financial IVR systems.
As shown in block 540, the system displays the one or more recommendations to the user, via the real-time user interface. In some embodiments, the system may also provide a single-click mechanism to automatically correct the error based on the one or more recommendations, where the single click mechanism comprises one or more code changes in the program code associated with the voice flow that the user is testing. In some embodiments, the system allows the user to test a second voice flow during the real-time voice interaction initiated by the user.
