The invention relates to a system and methods for routing a telephonic communication, and more particularly, for automatically routing future a telephone communication based on prior analytic attributes including customer demographic information.
It is known to utilize telephone call centers to facilitate the receipt, response and routing of incoming telephone calls relating to customer service, retention, and sales. A customer is in contact with a customer service representative (“CSR”) or CSR agent who is responsible for answering the customer's inquiries and directing the customer to the appropriate individual, department, information source, or service as required to satisfy the customer's needs. It is well known to monitor calls between a customer and agent. Accordingly call centers typically employ individuals responsible for listening to the conversation between the customer and the agent. While monitoring such calls may occur in real time, it is often more efficient and useful to record the call for later review.
Information gathered from the calls is typically used to monitor the performance of the CSR agents to identify any possible training needs. Based on a review and analysis of the conversation, a monitor will make suggestions or recommendations to improve the quality of a customer's experience.
In many instances, call centers receive calls from repeat customer. The repeat customer may require assistance with a new issue or additional assistance with a prior issue. However, a customer may also have had particularly favorable, or particularly poor prior interactions with a customer service representative or transaction experience during a prior call. This favorable or poor interaction may have been a result of behavioral or non-behavioral compatibility with the responding customer service representative, response time, lack of knowledge, inaccessibility to direct contact with a customer service representative or various other analytic attributes or factors.
Thus, there is a need in customer relationship management (“CRM”) for tools useful in improving the quality of future customer interactions with agents by intuitively and automatically routing future calls by the same customer to an appropriate communication destination; whether a self-service destination or a compatible customer service representative. In particular, a need exists for tools that will allow for future call routing based on data collected during prior calls.

Alternate implementations are included within the scope of the embodiments of the present invention in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those having ordinary skill in the art.
Generally, in terms of hardware architecture, as shown in
The processor 16 is a hardware device for executing software, particularly software stored in memory 18. The processor 16 can be any custom made or commercially available processor, a central processing unit (CPU), an auxiliary processor among several processors associated with the computer 12, a semiconductor based microprocessor (in the form of a microchip or chip set), a macroprocessor, or generally any device for executing software instructions. Examples of suitable commercially available microprocessors are as follows: a PA-RISC series microprocessor from Hewlett-Packard Company, an 80×8 or Pentium series microprocessor from Intel Corporation, Intel Xeon (Single and Dual Core), Intel Xeon Processor MP (Single and Dual Core), a PowerPC microprocessor from IBM, a Sparc microprocessor from Sun Microsystems, Inc., or a 8xxx series microprocessor from Motorola Corporation.
The memory 18 can include any one or a combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, etc.)) and nonvolatile memory elements (e.g., ROM, hard drive, tape, CDROM, etc.). Moreover, memory 18 may incorporate electronic, magnetic, optical, and/or other types of storage media. The memory 18 can have a distributed architecture where various components are situated remote from one another, but can be accessed by the processor 16.
The software in memory 18 may include one or more separate programs, each of which comprises an ordered listing of executable instructions for implementing logical functions. In the example of
The control system 14 may be a source program, executable program (object code), script, or any other entity comprising a set of instructions to be performed. When a source program, the program needs to be translated via a compiler, assembler, interpreter, or the like, which may or may not be included within the memory 18, so as to operate properly in connection with the O/S 24. Furthermore, the control system 14 can be written as (a) an object oriented programming language, which has classes of data and methods, or (b) a procedure programming language, which has routines, subroutines, and/or functions, for example but not limited to, C, C++, C# (C Sharp), PHP, Pascal, Basic, Fortran, Cobol, Perl, Java, and Ada. In one embodiment, the control system 14 is written in C++. The I/O devices 20 may include input devices, for example but not limited to, a keyboard, mouse, scanner, microphone, touch screens, interfaces for various medical devices, bar code readers, stylus, laser readers, radio-frequency device readers, etc. Furthermore, the I/O devices 20 may also include output devices, for example but not limited to, a printer, bar code printers, displays, etc. Finally, the I/O devices 20 may further include devices that communicate both inputs and outputs, for instance but not limited to, a modulator/demodulator (modem; for accessing another device, system, or network), a radio frequency (RF) or other transceiver, a telephonic interface, a bridge, a router, etc.
If the computer 12 is a PC, workstation, PDA, or the like, the software in the memory 18 may further include a basic input output system (BIOS) (not shown in
When the computer 12 is in operation, the processor 16 is configured to execute software stored within the memory 18, to communicate data to and from the memory 18, and to generally control operations of the computer 12 pursuant to the software. The control system 14 and the O/S 24, in whole or in part, but typically the latter, are read by the processor 16, perhaps buffered within the processor 16, and then executed.
When the control system 14 is implemented in software, as is shown in
In another embodiment, where the control system 14 is implemented in hardware, the control system 14 can be implemented with any or a combination of the following technologies, which are each well known in the art: a discrete logic circuit(s) having logic gates for implementing logic functions upon data signals, an application specific integrated circuit (ASIC) having appropriate combinational logic gates, a programmable gate array(s) (PGA), a field programmable gate array (FPGA), etc.
As may be seen in
According to the present invention, computer telephony integration (“CTI”) technology is provided. In a preferred embodiment discussed herein, CTI resides on a telephony server 207. However, it will be understood by those skilled in the art that CTI can reside on its own server or at other hardware described herein. Generally, in terms of hardware architecture, the telephony server 207 includes a processor, memory, and one or more input and/or output (I/O) devices (or peripherals) that are communicatively coupled via a local interface. The processor can be any custom-made or commercially available processor, a central processing unit (CPU), an auxiliary processor among several processors associated with the telephony server 207, a semiconductor based microprocessor (in the form of a microchip or chip set), a macroprocessor, or generally any device for executing software instructions. The memory of the telephony server 207 can include any one or a combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, etc.)) and nonvolatile memory elements (e.g., ROM, hard drive, tape, CDROM, etc.). The telephony server 207 may further include a keyboard and a mouse for control purposes, and an attached graphic monitor for observation of software operation. It will be understood that the telephony server may include standard CTI technology, such as that sold by Cisco, Avaya, Genesys or other provider of CTI providers.
According to one embodiment, the telephony server 207 also incorporates PBX control software to control the initiation and termination of connections between stations and via outside trunk connections to the PSTN 203. In addition, the software may monitor the status of all telephone stations 211 in real-time on the network and may be capable of responding to telephony events to provide traditional telephone service. This may include the control and generation of the conventional signaling tones such as dial tones, busy tones, ring back tones, as well as the connection and termination of media streams between telephones on the local network. Further, the PBX control software may use a multi-port module 223 and PCs to implement standard PBX functions such as the initiation and termination of telephone calls, either across the network or to outside trunk lines, the ability to put calls on hold, to transfer, park and pick up calls, to conference multiple callers, and to provide caller ID information. Telephony applications such as voice mail and auto attendant may be implemented by application software using the PBX as a network telephony services provider.
Referring to
The control processor 221 may include buffer storage and control logic to convert media streams from one format to another, if necessary, between the trunk interface 217 and local network. The trunk interface 217 provides interconnection with the trunk circuits of the PSTN 203. The local network interface 219 provides conventional software and circuitry to enable the telephony server 207 to access the local network. The buffer RAM and control logic implement efficient transfer of media streams between the trunk interface 217, the telephony server 207, the digital signal processor 225, and the local network interface 219.
The trunk interface 217 utilizes conventional telephony trunk transmission supervision and signaling protocols required to interface with the outside trunk circuits from the PSTN 203. The trunk lines carry various types of telephony signals such as transmission supervision and signaling, audio, fax, or modem data to provide plain old telephone service (POTS). In addition, the trunk lines may carry other communication formats such T1, ISDN or fiber service to provide telephony or multimedia data images, video, text or audio.
The control processor 221 manages real-time telephony event handling pertaining to the telephone trunk line interfaces, including managing the efficient use of digital signal processor resources for the detection of caller ID, DTMF, call progress and other conventional forms of signaling found on trunk lines. The control processor 221 also manages the generation of telephony tones for dialing and other purposes, and controls the connection state, impedance matching, and echo cancellation of individual trunk line interfaces on the multi-port PSTN module 223.
Preferably, conventional PBX signaling is utilized between trunk and station, or station and station, such that data is translated into network messages that convey information relating to real-time telephony events on the network, or instructions to the network adapters of the stations to generate the appropriate signals and behavior to support normal voice communication, or instructions to connect voice media streams using standard connections and signaling protocols. Network messages are sent from the control processor 221 to the telephony server 207 to notify the PBX software in the telephony server 207 of real-time telephony events on the attached trunk lines. Network messages are received from the PBX Switch 205 to implement telephone call supervision and may control the set-up and elimination of media streams for voice transmission.
The local network interface 219 includes conventional circuitry to interface with the local network. The specific circuitry is dependent on the signal protocol utilized in the local network. In one embodiment, the local network may be a local area network (LAN) utilizing IP telephony. IP telephony integrates audio and video stream control with legacy telephony functions and may be supported through the H.323 protocol. H.323 is an International Telecommunication Union-Telecommunications protocol used to provide voice and video services over data networks. H.323 permits users to make point-to-point audio and video phone calls over a local area network. IP telephony systems or VoIP can be integrated with the public telephone system through a local network interface 219, such as an IP/PBX-PSTN gateway, thereby allowing a user to place telephone calls from an enabled computer. For example, a call from an IP telephony client to a conventional telephone would be routed on the LAN to the IP/PBX-PSTN gateway. The IP/PBX-PSTN gateway translates H.323 protocol to conventional telephone protocol and routes the call over the conventional telephone network to its destination. Conversely, an incoming call from the PSTN 203 is routed to the IP/PBX-PSTN gateway and translates the conventional telephone protocol to H.323 protocol.
As noted above, PBX trunk control messages are transmitted from the telephony server 207 to the control processor 221 of the multi-port PSTN. In contrast, network messages containing media streams of digital representations of real-time voice are transmitted between the trunk interface 217 and local network interface 219 using the digital signal processor 225. The digital signal processor 225 may include buffer storage and control logic. Preferably, the buffer storage and control logic implement a first-in-first-out (FIFO) data buffering scheme for transmitting digital representations of voice audio between the local network to the trunk interface 217. It is noted that the digital signal processor 225 may be integrated with the control processor 221 on a single microprocessor.
The digital signal processor 225 can include a coder/decoder (CODEC) connected to the control processor 221. The CODEC may be a type TCM29c13 integrated circuit made by Texas Instruments, Inc. In one embodiment, the digital signal processor 225 receives an analog or digital voice signal from a station within the network or from the trunk lines of the PSTN 203. The CODEC converts the analog voice signal into in a digital from, such as digital data packets. It should be noted that the CODEC is not used when connection is made to digital lines and devices. From the CODEC, the digital data is transmitted to the digital signal processor 225 where telephone functions take place. The digital data is then passed to the control processor 221 which accumulates the data bytes from the digital signal processor 225. It is preferred that the data bytes are stored in a first-in-first-out (FIFO) memory buffer until there is sufficient data for one data packet to be sent according to the particular network protocol of the local network. The specific number of bytes transmitted per data packet depends on network latency requirements as selected by one of ordinary skill in the art. Once a data packet is created, the data packet is sent to the appropriate destination on the local network through the local network interface 219. Among other information, the data packet contains a source address, a destination address, and audio data. The source address identifies the location the audio data originated from and the destination address identifies the location the audio data is to be sent.
The system permits bidirectional communication by implementing a return path allowing data from the local network, through the local network interface 219, to be sent to the PSTN 203 through the multi-line PSTN trunk interface 217. Data streams from the local network are received by the local network interface 219 and translated from the protocol utilized on the local network to the protocol utilized on the PSTN 203. The conversion of data may be performed as the inverse operation of the conversion described above relating to the IP/PBX-PSTN gateway. The data stream is restored in appropriate form suitable for transmission through to either a connected telephone 211, 215 or an interface trunk 217 of the PSTN module 223, or a digital interface such as a T1 line or ISDN. In addition, digital data may be converted to analog data for transmission over the PSTN 203.
Generally, the PBX switch of the present invention may be implemented with hardware or virtually. A hardware PBX has equipment located local to the user of the PBX system. The PBX switch 205 utilized may be a standard PBX manufactured by Cisco, Avaya, Siemens AG, NEC, Nortel, Toshiba, Fujitsu, Vodavi, Mitel, Ericsson, Panasonic, or InterTel. In contrast, a virtual PBX has equipment located at a central telephone service provider and delivers the PBX as a service over the PSTN 203.
The Recording Server
As illustrated in
Generally, hardware architecture is the same as that discussed above and shown in
In one preferred embodiment, the recording server 209 incorporates recording software for recording a telephone signal based on the source address and/or destination address of the signal. The method utilized by the recording server 209 depends on the communication protocol utilized on the communication lines to which the recording server 209 is coupled. The signal carrying audio data of a communication between at least two users can be an analog signal or a digital signal in the form of a network message. In one embodiment, the signal is an audio data transmitted according to a signaling protocol, for example the H.323 protocol described above.
One example of a recording method that may be used in the present system is illustrated in
Similar to the process described above, when the call center agent speaks, their voice is digitized (if needed) and converted into digital data packet 235 according to the communication protocol utilized on the local network. The data packet 235 comprises a source address identifying the address of the call center agent, a destination address identifying the address of the outside caller, and second constituent audio data comprising at least a portion of the call center agent's voice. The data packet 235 is received by the local network interface 219 and translated from the communication protocol utilized on the local network to the communication protocol utilized on the PSTN 203. The conversion of data can be performed as described above. The data packet 235 is restored in appropriate form suitable for transmission through to either a connected telephone 211, 215 or an interface trunk 217 of the PSTN module 223, or a digital interface such as a T1 line or ISDN. In addition, digital data can be converted to analog data for transmission through the PSTN.
The recording server 209 receives either a data packet 235 comprising: the source address identifying the address of the outside caller, a destination address identifying the address of the call center agent, and the first constituent audio data comprising at least a portion of the outside callers voice; or a data packet 235 comprising a source address identifying the address of the call center, a destination address identifying the address of the outside caller, and second constituent audio data comprising at least a portion of the customer's agent voice. It is understood by one of ordinary skill in the art that the recording server 209 is programmed to identify the communication protocol utilized by the local network and extract the audio data within the data packet 235. In one embodiment, the recording server 209 can automatically identify the utilized communication protocol from a plurality of communication protocols. The plurality of communication protocols can be stored in local memory or accessed from a remote database.
The recording server 209 comprises recording software to record the communication session between the outside caller and a call center agent in a single data file in a stereo format. The first data file 241 has at least a first audio track 237 and a second audio track 237. Once a telephone connection is established between an outside caller and a call center agent, the recording software creates a first data file 241 to record the communication between the outside caller and the call center agent. It is contemplated that the entire communication session or a portion of the communication session can be recorded.
Upon receiving the data packet 235, the recording server 209 determines whether to record the audio data contained in the data packet 235 in either the first audio track 237 or the second audio track 239 of the first data file 241 as determined by the source address, destination address, and/or the audio data contained within the received data packet 235. Alternatively, two first data files can be created, wherein the first audio track is recorded to the one of the first data file and the second audio track is recorded to the second first data file. In one embodiment, if the data packet 235 comprises a source address identifying the address of the outside caller, a destination address identifying the address of the call center agent, and first constituent audio data, the first constituent audio data is recorded on the first audio track 237 of the first data file 241. Similarly, if the data packet 235 comprises a source address identifying the address of the call center agent, a destination address identifying the address of the outside caller, and second constituent audio data, the second constituent audio data is recorded on the second audio track 239 of the first data file 241. It should be noted the first and second constituent audio data can be a digital or analog audio waveform or a textual translation of the digital or analog waveform. The recording process is repeated until the communication link between the outside caller and call center agent is terminated.
As noted above, the recording server 209 can be connected to the trunk lines of the PSTN 203 as seen in
Once the communication link is terminated, the recording server 209 ends the recording session and stores the single data file having the recorded communication session in memory. After the first data file is stored in memory, the recording server 209 can extract either or both of the first constituent audio data from the first audio track of the first data file or the second constituent audio data from the second audio track of the first data file. In one embodiment, the first constituent audio data extracted from the first audio track is stored in a first constituent data file 243. Similarly, the second constituent audio data extracted from the second audio track can be stored in a second constituent data file 245. The first and second constituent data files 243, 245 can be compressed before being stored in memory. The extracted data can be in the form of a digital or analog audio waveform or can be a textual translation of the first or second constituent audio data. It is contemplated that either or both of the first constituent data file 243 or the second constituent data file 245 can be further analyzed or processed. For example, among other processes and analyses, filtering techniques can be applied to the first constituent data file and/or the second constituent data file. Moreover, event data, such as silence periods or over-talking, can be identified through analysis techniques known to those skilled in the art.
Further, as illustrated in
It is known in the art that “cradle-to-grave” recording may be used to record all information related to a particular telephone call from the time the call enters the contact center to the later of: the caller hanging up or the agent completing the transaction. All of the interactions during the call are recorded, including interaction with an IVR system, time spent on hold, data keyed through the caller's key pad, conversations with the agent, and screens displayed by the agent at his/her station during the transaction.
As shown in
It is contemplated by the present invention that mining and analysis in accordance with the present invention can be applied directly to voice data configured in audio format. Preferably, however, the voice data to be mined and analyzed is first translated into a text file. It will be understood by those of skill that the translation of audio to text and subsequent data mining may be accomplished by systems known in the art. For example, the method of the present invention may employ software such as that sold under the brand name Audio Mining SDK by Scansoft, Inc., or any other audio mining software suitable for such applications.
In one embodiment of the present invention, the voice data is mined for behavioral signifiers associated with a linguistic-based psychological behavioral model. In particular, the voice data is searched for text-based keywords (i.e., behavioral signifiers) relevant to a predetermined psychological behavioral model. One preferred such psychological behavioral model and behavioral analysis is described in commonly assigned U.S. patent application Ser. No. 11/131,486, which is incorporated herein by reference.
As shown in
In addition to the behavioral assessment of voice data, the method of the present invention may also employ distress analysis of voice data. Linguistic-based distress analysis is preferably conducted on both the textual translation of the voice data and the audio file containing voice data. Accordingly, linguistic-based analytic tools as well as non-linguistic analytic tools may be applied to the audio file. For example, one of skill in the art may apply spectral analysis to the audio file voice data while applying a word spotting analytical tool to the text file. Linguistic-based word spotting analysis and known algorithms for identifying distress can be applied to the textual translation of the communication. Preferably, the resultant distress data is also stored in the customer history database 302 for subsequent analysis of the communication and use in call routing.
It is also often desirable to analyze non-linguistic phone events occurring during the course of a conversation such as hold times, transfers, “dead-air,” overtalk, etc. Accordingly, in one embodiment of the present invention, phone event data resulting from analysis of these non-linguistic events is generated. As shown in
According to a preferred embodiment of the invention shown in
Generally, call assessment data 58 is comprised of behavioral assessment data 55, phone event data 70 and distress assessment data 72. The resultant call assessment data 58 may be subsequently viewed to provide an objective assessment or rating of the quality, satisfaction or appropriateness of the interaction between an agent and a customer. The call assessment data 58 may generate resultant data that is also useful for characterizing the success of the interaction between a customer and an agent and for determining desired routing of subsequent phone calls from the same customer.
According to the present invention, the system can employ a word-spotting algorithm that categorizes communications into particular types or categories based on words used in the communication. In one embodiment, each communication is automatically categorized as a service call type (e.g., a caller requesting assistance for servicing a previously purchased product), a retention call type (e.g., a caller expressing indignation, or having a significant life change event), or a sales call type (e.g., a caller purchasing an item offered by a seller). In one scenario, it may be desirable to analyze all of the “sales call type” communications received by a contact center during a predetermined time frame. In that case, the user would analyze each of the sales call type communications from that time period by applying the predetermined psychological behavioral model to each such communication.
Alternatively, the communications may be grouped according to customer categories, and the user may desire to analyze the communications between the call center and communicants within a particular customer category. For example, it may be desirable for a user to perform an analysis only of a “platinum customers” category, consisting of high end investors, or a “high volume distributors” category comprised of a user's best distributors.
As shown in
Thus, according to one embodiment of the present invention, the system includes and IVR system 206 a telephone switch 205, a recording server 209 and a routing server 300. The IVR system 206 is configured to receive telephonic communications and caller commands. The IVR system 206 is also configured to communicate with a telephone switch 205 and a routing server 300. The telephone switch 205 is configured to route a telephonic communication to one of a plurality of communication destination addresses.
According to one embodiment of the present invention, the recording server 209 is operably coupled, and in operable communication with the routing server 300. As discussed above, the recording server 209 is configured to record a telephonic communication between a caller and a customer service representative. The recording server 209 uses logic to perform the recording functions as described above. As previously noted, the logic can be in the form of hardwired logic gates or software. Thus, logic is provided to generate behavioral assessment data as discussed above. According to one embodiment shown in
The Routing Server
As illustrated in
Generally, hardware architecture is the same as that discussed above and shown in
As noted above, the routing server 300 incorporates software for receiving a transmitted customer identifier. The customer identifier can be received from an IVR, directly from the PSTN 203 or from other input device. The routing server 300 also incorporates software for sending instructions for routing a telephonic communication to an appropriate communication destination address based on certain criteria. More particularly, the routing server 300 is configured to receive a customer identifier. It will be understood that the customer identifier may be generated by any conventional means, including but not limited to, automatic number identification (ANI), voice portal prompted variables, IP addresses or any other suitable identifiers.
The routing server 300 determines whether the received customer identifier corresponds to a stored customer identifier in a customer history database 302. As discussed herein, the customer history database 302 is configured to store historic data. That historic data is associated with at least one recorded telephonic communication having a corresponding stored customer identifier. The stored historic data is comprised of at least one of the following: call type data, distress assessment data, behavioral assessment data, call preference data and customer profile.
The routing server 300 also analyzes the historic data corresponding to the received customer identifier and the stored customer identifier. The telephonic communication is associated with one of a plurality of communication destination addresses. This association step is based on the analysis of the historic data. Finally, the routing sever 300 transmits a signal identifying the associated communication destination address. This signal may be transmitted directly to a switch mechanism or through CTI.
According to one embodiment of the present invention, the routing server 300 compares a stored customer profile with a customer service representative profile. In this manner, the system or software of the present invention can include in a call routing analysis consideration of a scored comparison of the compatibility of the customer with the customer service representative. The customer profile score can be generated as a result of an analysis of various one or ones of demographic identifiers associated with a customer and a customer service representative. Accordingly, in one preferred embodiment in which the customer profile score is based on a personality (derived from the behavioral assessment data) and gender match, the scoring may be allocated according to the following scale in Table 1:
The routing server 300 can be, according to one embodiment, configured to transmit an audible message based on the association of the telephonic communication with a communication destination address. Accordingly, it is contemplated that upon selection of an appropriate communication destination address to which a telephonic communication will be routed, the system indicates to the customer the ultimate destination of the telephonic communication. It will be understood that the audible message is not limited to an indication of the communication destination address, but instead may communicate other information relating to the analysis of the customer history database.
It is also useful to gather an understanding of the number of transactions that a customer associated with a customer identifier has completed in IVR or another interface (such as a web interface). In particular, such information can be useful in determining whether to route a customer telephonic communication through IVR or directly to a customer service representative agent. Thus, according to one embodiment of the present invention, the system further determines the number of previously completed transactions in IVR corresponding to a received customer identifier.
According to one embodiment of the invention, the system is further configured to generate a customer route record. The route record will include relevant information about the caller and the call activity. For example, the route record may include information relating to the call frequency, call type, the customer profile, the customer behavioral assessment data and distress assessment data. It will be understood that the route record can include other data relevant to the customer's interaction with a customer service representative agent or call center.
Using information from the customer route record, the system can generate audible messages appropriate for the customer during subsequent interactions. For example, an audible message relating to call type may be generated that states, “if you are calling about your previous [call type] on [date], please press 1.” As another example, an audible message relating to a customer's previous distress assessment data may be generated to state, “we understand you may have had an unsatisfactory experience in a call on [date]; recognizing your importance to us, we are routing your call to a specialized group of customer service representatives.”
Thus, the present invention allows for automatic call routing based on past indicators and analytic attributes. The following chart (Table 2) outlines exemplary experiences of a customer during an interaction as a result of various analytic outputs.
While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention, and the scope of protection is only limited by the scope of the accompanying claims.
