Abstract:
An automated voice-based customer service system assists TV subscribers without engaging a customer service representative at a call center. A spoken user query is captured by a hand-held remote control device equipped with a microphone. The remote control device transmits voice data to a television content receiver and the voice data is sent to an automated customer service system. The automated customer service system decodes the user query and formulates a response. The response is then transmitted back to the television content receiver for presentation to the user as a voice response, on-screen text response, or as a modification to equipment settings. The user is able to converse verbally with the voice-based automated customer service system. Such a protocol assists subscribers in solving most common, routine problems without involvement of a human customer service representative. The automated customer service system can be programmed to process user queries about billing as well as technical difficulties concerning content reception, tuning, or display of television signals, and device connectivity.

Description:
BACKGROUND 
       [0001]    Technical Field 
         [0002]    The present disclosure generally relates to automated customer service systems and, in particular, to an automated customer service that provides voice recognition capability so that a human customer service representative is not needed to serve the needs of television subscribers. 
         [0003]    Description of the Related Art 
         [0004]    Watching television has become a complicated process that requires viewers to be adept at navigating menus, remote control buttons, and feature settings. Adjusting TV-related settings is a major source of frustration for many viewers. In particular, elderly viewers may have difficulty reading and interpreting icons on remote control buttons and manipulating the buttons to step through menus displayed on the TV screen. In order to preserve their subscriber base, TV content providers (e.g., Dish Network®) maintain call centers to field customer service calls from subscribers regarding installed subscriber equipment. In response to a real or perceived equipment failure or an operational anomaly, a TV subscriber may contact the TV content provider customer service department, by telephone or e-mail. 
         [0005]    Customer service is now one of the largest business expenses for TV content providers. One reason customer service is so expensive is that calls are fielded by human customer service representatives (CSRs). Yet, most TV service calls are for routine problems that are easy to troubleshoot and could be solved in an automated fashion without involving a human being. For example, historical records among TV content providers indicate that some of the most common customer service complaints are solved by simply replacing the subscriber&#39;s remote control batteries. 
         [0006]    In the past, customer service protocols have been automated using a numerical telephone keypad as an interactive device. When a customer places a service call, choices are presented to the customer by a telephone recording. The call is then routed according to customer selections made by entering a number, or in some cases, by speaking a number or a prescribed phrase, with limited voice recognition. For example, a telephone caller may be directed through a series of menus to provide information about their problem and equipment set-up, so that initial steps of troubleshooting can be performed automatically without engaging the customer service representative. However, such a system can become another source of customer frustration, which just adds to subscriber dissatisfaction instead of alleviating it. As a result, subscribers often attempt to bypass the menu-driven telephone automation system so they can speak directly to a human customer service representative. 
       BRIEF SUMMARY 
       [0007]    A system is disclosed that provides fully automated voice-based customer service to TV subscribers without engaging a customer service representative at a call center. A spoken user query is captured by a hand-held remote control device equipped with a microphone. The remote control device can be in the form of a traditional remote control, or, for example, a smart phone programmed with remote control functions. The remote control device transmits voice data to a remote automated customer service system, e.g., a cloud-based system. The automated customer service system decodes the user query and formulates a response. Formulating the response may entail consulting a health server system database that monitors the customer&#39;s subscriber equipment status, or a weather database that monitors conditions at the customer&#39;s location. The response is then transmitted back to the remote control for presentation to the user as a voice response. In this way, the user is able to converse verbally with the automated customer service system. Such a protocol can provide assistance to subscribers to solve a majority of common, routine problems without involvement of a human customer service representative. The automated customer service system can be programmed to process user queries about billing as well as technical problems concerning content reception, tuning, or display of television signals. The automated customer service system disclosed is also suitable for use in businesses other than media content providers.

         [0025]    Specific embodiments are described herein with reference to automated customer service systems that have been produced; however, the present disclosure and the reference to certain materials, dimensions, and the details and ordering of process steps are exemplary and should not be limited to those shown. 
         [0026]    Turning now to the drawings,  FIG. 1  illustrates an exemplary media subscription service environment that includes a content receiver system  200  and an automated customer support system  250 , according to one embodiment. A basic content receiver system  200  includes a content receiver  202 , also called a set top box  202  in some systems, communicatively coupled to a source of media content, for presentation on a display  204 . The media content is provided as a media signal  201 . The automated customer support system  250  connects the subscriber  224  to a source of ongoing support for subscriber equipment, including both hardware and software, supplied by a media content provider. 
         [0027]    In the exemplary embodiment shown in  FIG. 1 , the content receiver system  200  is a home media entertainment system, the media signal  201  is a satellite signal received by the rooftop-mounted satellite receiving antenna  206 , and the automated customer support system  250  is associated with a satellite television subscription service. The content receiver is a set top box  202  that receives media content from the satellite receiving antenna  206  via a communication link  208 . 
         [0028]    While the set top box  202  is described herein as being connected to a satellite receiving antenna  206 , in other embodiments the set top box  202  can receive media content from other sources. For example, the set top box  202  can receive media content via an antenna that receives terrestrial broadcast signals. Alternatively, the set top box  202  can receive media content via the media signal  201  received via a broadband cable subscriber service. Additionally or alternatively, the set top box  202  can receive media content via the media signal 
         [0029]      201  received directly from the Internet  212  via a network communication link  210 , using an Internet-based media subscription service such as, for example, Netflix®, Hulu®, Amazon Prime®, or the like. Furthermore, a content provider may provide to the subscriber multiple media signals  201  via satellite (as shown) and/or via the Internet, broadband cable and/or Internet, or in any other suitable way. 
         [0030]    The set top box  202  can be coupled to a television, or the set top box  202  can be in the form of hardware built into a television, wherein the set top box receives content from the media content provider. Alternatively, the set top box  202  can be any electronic device that receives media content by accessing the Internet  212 ; for example, a gaming console, a smart phone, a tablet computer, a laptop computer, or a desktop computer. 
         [0031]    The display  204  can be any kind of video display device such as a cathode ray tube display, a liquid crystal display (LCD), a plasma display, a television, a computer monitor, a rear projection screen, a front projection screen, a heads-up display, or any other electronic display device. The display  204  can include audio speakers, or the display  204  can be coupled to separate audio speakers. The term “for display” as used herein generally includes presentation of an audio component as well as a video component of the media signal  201 . 
         [0032]    The communication links  208  and  210  typically are wired connections such as one or more coaxial cables. One skilled in the art will recognize that other methods and other systems of delivering the media signal  201  to the set top box  202  may be possible. For example, one or both of the communication links  208  and  210  can be wireless links. 
         [0033]    The content receiver  202  optionally further includes one or more peripheral devices  220  such as a media playback device including, but not limited to, a DVD player, a VCR, a stereo, a television, a game console, or a stand-alone DVR device that provides an alternate source of content directly to the display  204  via a wireless or a wired connection  222 . Any of the peripheral devices  220  can be subscriber-owned devices, or they can be supplied by the media subscription service. When a peripheral device  220  is subscriber-owned, the subscription service as described herein may provide support for interfacing other components of the content receiver system  200  and the automated customer support system  250  to the subscriber-owned peripheral device  220 . 
         [0034]    The remote control  226  can be operated by a user, for example, the subscriber  224 , to cause the set top box  202  to present received content on the display  204 . The remote control  226  may also be used by a viewer to display a programming guide and to communicate program selections to the set top box  202 . The remote control  226  is communicatively coupled to the set top box  202  via a wireless path  228 , for example, an infrared (IR) signal, Bluetooth® signal, or the like. The remote control  226  can be used to send commands to the satellite set top box  202 , including channel selections, display settings, and DVR instructions. The wireless path  228  can use, for example, infrared or UHF transmitters within the remote control  226 . One example of an embodiment of the remote control  226  is the EchoStar Technologies Corporation 40.0 Remote Control that includes an IR transmitter and an ultra-high frequency (UHF) transmitter. The remote control  226  may be able to send signals to the peripheral devices  220  that form part of the content receiver system  200 . The set top box  202  may also be able to send signals to the remote control  226 , including, but not limited to, signals to configure the remote control  226  to operate the other peripheral devices in the content receiver system  200 . In some embodiments, the remote control  226  has a set of Light Emitting Diodes (LEDs). Some remote controls can include Liquid Crystal Displays (LCDs) or other screens. The remote control  226  can include buttons, dials, or other man-machine interfaces. While the remote control  226  can often be the common means for a user to communicate with the satellite set top box  202 , one skilled in the art will recognize that other means of communicating with the set top box  202  are available, including, but not limited to, attached keyboards, smart phones, front panel buttons or touch screens. 
         [0035]    The satellite receiving antenna  206  receives media content via the media signal  201  from one or more satellite transponders in earth orbit. Each satellite transponder is, for purposes of the content receiver system  200 , a source of content that transmits one or more media channels, such as HBO, ESPN, pay-per-view channels, etc., to the satellite receiving antenna  206 . A satellite television distributor can transmit one or more satellite television signals to one or more satellites. Satellite television distributors can utilize several satellites to relay the satellite television signals to the subscriber  224 . Each satellite can have several transponders. Transponders transmit the satellite signal from the satellite to the satellite receiving antenna  206 . 
         [0036]    The satellite receiving antenna  206  can focus the satellite signal on one or more low-noise block filters (LNBF), also referred to as low-noise block down converters (LNBDC). The LNBFs can de-polarize and initially process the signal. This initial processing can include filtering noise from the signal and down-converting the signal. Down-conversion is sometimes required to transmit the satellite signal through the communication link  208 . 
         [0037]    The set top box  202  is also coupled, by the network communication link  210 , to remotely-located elements of the Internet-based automated customer service system  250 , as described herein with reference to  FIG. 3 . The automated customer service system  250  may further have access to an existing equipment health server, interactive voice response (IVR) system, and customer service call center. Such a customer service call center provides a staff of human customer service representatives (CSRs) in case a subscriber query cannot be handled in an automated fashion. 
         [0038]      FIG. 2  shows components of a typical set top box  202  that is used in combination with an embodiment of the present disclosure. Components of the set top box  202  include control circuitry  302 , one or more tuning devices  304 , an optional internal digital video recorder (DVR)  306 , a memory  308 , a network interface  310 , a peripheral interface  312 , and a remote control interface  314 . 
         [0039]    Generally, the set top box  202  can receive one or more television signals from a media provider such as a cable television distributor, a broadcast television distributor or a satellite television distributor. In the embodiment shown, the content receiver system  200  receives signals from a satellite television distributor via the satellite set top box  202 . One skilled in the art will recognize that set top box  202  can also receive video from digital subscriber line (DSL), Internet, wireless and other signals from content or video distributors. The set top box  202  can process television signals and can send the processed signals to peripheral electronic devices, such as the display  204  and the remote control  226 . The set top box  202  also can accept commands from the remote control  226  or other peripheral electronic devices. More detail about the functionality of the set top box  202  is provided below. One skilled in the art will recognize that many embodiments of the content receiver system  200  are possible and within the scope of this disclosure. Other such embodiments can include, but are not limited to, various combinations or permutations of devices and connections for the delivery, storage, and display of communications, content and other data. 
         [0040]    In one embodiment, the set top box  202  receives media content from the satellite receiving antenna  206 . The tuning device  304  tunes into a selected media channel received by the satellite receiving antenna  206  to acquire a satellite signal. The tuning device  304  can initially process the satellite signal. The tuning device  304  can also receive subscriber commands in the form of signals from the control circuitry  302 . Signals from the control circuitry  302  can include, but are not limited to, a signal to tune to a transponder as part of the process of selecting a certain channel for viewing on a peripheral device. The tuning device  304  transmits the acquired satellite signal to the control circuitry  302  where the signal can undergo extensive signal processing. 
         [0041]    Furthermore, the set top box  202  can include multiple tuning devices  304 . This allows the set top box  202  to record two or more programs that air simultaneously. Generally, the set top box  202  can record one show at a single time for each tuning device  304  that the set top box  202  includes. For example, if the set top box  202  includes two tuning devices  304 , then the set top box  202  can record two media programs simultaneously. Thus if there is a recording conflict between two programs, the set top box  202  can still record both programs because it has two tuners. If a recording conflict occurs because the number of tuning devices  304  is less than the number of programs that the subscriber  224  wants to view or record, the control circuitry  302  can be programmed to resolve the conflict by prioritizing certain media content according to the subscriber&#39;s directions, or automatically, based on various criteria. 
         [0042]    A first step in signal processing by the control circuitry  302  can include, for example, demodulating the satellite signal. Further signal processing can include error checking. One skilled in the art will recognize that systems with analog data or combined analog and digital data are also possible and contemplated herein. 
         [0043]    The DVR  306  can be used to record programs locally in the set top box  202 . For example, while viewing the programming guide the user may notice a TV show that is not broadcast at a convenient time. By using the remote control  226  the user can command the set top box  202  to record the TV show to the DVR  306  so that the user may view the TV show at a later convenient time. When the user selects a program to be recorded to the DVR, the set top box  202  sets a recording timer that causes the set top box  202  to automatically record the selected program at the scheduled time. At a time convenient to the user, the user can operate the remote control  226  to cause the set top box  202  to display a list of programs that have been recorded to the DVR. The user can select the desired program from the list of recorded programs, and the set top box  202  will play back the selected program. 
         [0044]    Alternatively, the set top box  202  may access, via the Internet  212 , recorded programs stored on a remote storage device. In this case, when the user of the set top box  202  selects a media program to be recorded, the media program is recorded to remote storage instead of to the DVR  306  inside the set top box  202 . The user of the set top box  202  can schedule media program recordings by accessing the Internet  212  through a smart phone, a PC, a tablet, a laptop, or other suitable means. The user can log into an account associated with the set top box  202  and can schedule recordings via the Internet  212 . The media programs can be viewed by connecting the set top box  202  to the Internet  212  to access the remote storage device. 
         [0045]    As the user selects multiple programs to be recorded to the DVR  306 , it is possible that two or more of the media programs will have a time conflict in their scheduled air times. When the set top box  202  determines that there is a time conflict between two media programs which are both scheduled to be recorded, the set top box  202  follows a particular protocol to automatically assign respective priority levels to the two media programs. The media program that has a higher priority will be recorded at the expense of the media program that has the lower priority if the conflict cannot be resolved. The set top box  202  can store in the memory  308  instructions that operate the DVR  306  according to such a protocol. 
         [0046]    The satellite set top box  202  can be connected to the display  204  and the peripheral devices  220  through a peripheral interface  312 . Such peripheral devices can send and receive signals to and from the satellite set top box  202 . For instance, a television can receive video and audio signals, whereas a stereo can receive only audio signals. A camcorder, on the other hand, can send video or audio signals to the satellite set top box  202  or receive audio and video signals from the set top box  202  to record. As another example, the peripheral interface  312  can include a microprocessor and associated electronic components to permit an interface to content security devices such as an external smart card. The peripheral interface  312  can then encrypt or decrypt content for output to other peripheral devices. Thus, the peripheral interface  312  can perform one or more functions for multiple peripheral devices, including, but not limited to, the synchronous or asynchronous transfer of data between different peripheral devices (e.g., decrypting content using a smart card peripheral device and outputting decrypted content to a television at the same time). One skilled in the art will recognize that the peripheral devices can include many types of commercially available electronic devices. 
         [0047]    Another peripheral device and connection to the satellite set top box  202  can include a phone line and modem. Set top box  202  can use a modem and phone line to communicate with one or more outside entities or systems (e.g., satellite television distributor). The phone line can carry local or long-distance telephone service. One skilled in the art will recognize that the phone line can also carry other services, including, but not limited to, DSL service. These communications can include requesting pay-per-view programming, reporting of purchases (for example, pay-per-view purchases), obtaining updates to subscriber programming (e.g., updating EPG data), or receiving updates to software on the satellite set top box  202 . For example, the phone line can communicate with the satellite set top box  202  using an RJ-11 style telephone connection. One skilled in the art will recognize that there are many other uses for this phone line connection. For example, EPG data can be transmitted to set top box  202  via a phone line or in the medial signal  201 . One skilled in the art will recognize that the EPG data can be transmitted to set top box  202  by various other methods, systems and outside entities. Also, one skilled in the art will recognize that a phone line connection to the media content provider can represent other communication connections, including, but not limited to, wireless, Internet, or microwave communications connections. Another function of the phone line can be to periodically receive the EPG data. One skilled in the art will also recognize that a phone line connection can permit networked communications with other network-ready devices using the telephone wiring within a subscriber&#39;s location. 
         [0048]    The network interface  310  provides network connectivity, for example, to the Internet  212  via a wireless router or a local area network. The peripheral interface  312  can include components that permit connection of RJ-45 network cabling and transmission of TCP/IP traffic to other connected devices. As another example, a wireless router can be attached via the peripheral interface  312  to allow wireless local-area-network (WLAN) data communications using a standard wireless networking protocol such as WiMAX, 802.11b or 802.11g. One skilled in the art will recognize that various other network connections to the set top box  202  are possible. 
         [0049]    The remote control interface  314  includes instructions that allow a user to communicate with the satellite set top box  202 , and can be implemented using the peripheral interface  312  or by connecting a separate remote control interface device. The remote control interface  314  can translate an input from the user into a format understandable by the control circuitry  302 . The remote control interface  314  can thus be considered a user interface (UI). The translation systems can include, but are not limited to, electronic receivers and electronic relays. The remote control interface  314  can receive commands from more than one remote control  226 . The remote control  226  can use infrared, UHF, or other communications technology. The remote control  226  can include a microphone, for example, a condenser microphone for receiving voice commands, and/or a built-in speaker. One skilled in the art will recognize that other means to receive and translate user inputs are possible. 
         [0050]    It is in the interest of the media content provider to ensure that the subscriber  224  has a very good experience obtaining customer service, and thus continues to use the media content provider for the long term, paying their subscription fee and encouraging others to subscribe. To provide a good experience, the content provider will want to ensure that as few problems with the subscriber equipment occur as possible and, in the event problems do occur, to solve the problems quickly and also make the subscriber  224  feel that a high quality of customer service is being provided. 
         [0051]    One way to provide high-quality customer service is to have a large number of service representatives and a large number of call centers standing by at all times to immediately handle any phone calls that come in describing problems with the service being provided. Unfortunately, creating call centers costs money, since telephone lines, desks, and office space needs to be provided. In addition, each call service representative requires training as well as continued pay and benefits for providing customer support. It is therefore desirable to provide highly qualified and well-trained customer service representatives but to ensure that they only deal with the major problems which cannot be solved by other techniques as described herein according to the various embodiments. 
         [0052]    One such technique entails monitoring the hardware components or associated software described above with reference to  FIG. 2  by a remote health server for signs of failure or faulty operation, and storing monitor data in an associated health server database. Such a health server is described, for example, in U.S. patent application Ser. No. 14/185,723. The remote health server and the health server database are located at a content provider location or a third party server facility that is remote from the location of the content receiver system  200 . Information stored in the remote health server is accessible by the content provider, but not by the subscriber. Monitor data stored in the health server database can be forwarded to one or more other remote servers for use in responding to an automated customer service call. 
         [0053]      FIG. 3  shows an exemplary automated customer service system  250  providing assistance to television subscribers on request. In one embodiment, the automated customer service system  250  includes the television content receiver or set top box  202  and the remote control  226 , equipped with a microphone  351  and, optionally, a built-in speaker  352 . 
         [0054]    The Automated Customer Service (ACS) system  250  further includes a first server that is an automatic speech recognition (ASR) server  353 , and a second server that is an intent recognition (IR) server  355 . The content receiver  202  is communicatively coupled to the ASR server  353  and the IR server  355  by a network such as the Internet  212 . 
         [0055]    The ASR server  353  is equipped with an ASR engine  354  that performs automated speech recognition, and the IR server  355  is equipped with an intent recognition (IR) engine  356  to perform intent recognition, according to the arrangement shown in  FIG. 3 . The ASR engine  354  can be in the form of coded instructions for execution by a microprocessor within the ASR server  353 . The ASR engine  354  can perform speech recognition functions implemented as code or as specialized electronic hardware components. For example, the ASR engine  354  can perform the speech recognition functions by using either a general-purpose microprocessor programmed with speech recognition instructions, or by using a dedicated voice recognition controller unit. In one embodiment, the ASR engine  354  is provided by a third party, for example, an existing provider of speech recognition services such as Nuance Communications, Inc. of Burlington, Mass. In such an embodiment, the ASR server  353  also functions as a web server and the automatic speech recognition function is performed by a web-based application that receives input through a web site. The ASR server  353  can be a cloud-based server located anywhere, and coupled to the set top box  202  via the Internet  212  or via a direct satellite connection. The ASR server  353  can be coupled to the Internet  212  by either a wired or a wireless ACS signal path  357 . The ASR server  353  may also perform additional functions related to speech recognition. 
         [0056]    In one embodiment, speech recognition capability is provided by the provider of the entertainment content i.e., by a satellite TV or cable TV content provider, in the form of speech recognition instructions and/or a voice recognition controller unit within the ASR server  353  that is built into the content receiver  202 , or located remotely from the content receiver as shown in  FIG. 3 . 
         [0057]    In one embodiment, when a smart phone is configured for use as the remote control  226 , voice recognition capability on board the smart phone, or provided by the smart phone service provider, can perform the function of the ASR engine  354  locally. 
         [0058]    In one embodiment, the IR server  355  is located at a remote data center, for example, at a cloud-based server farm that includes a data repository. The IR engine  356 , in the form of coded instructions for execution by a processor within the IR server  355 , can be provided by a third party, for example, data analytics software available from Rovi Corporation of Santa Clara, Calif. Furthermore, the IR server  355  that is equipped with the IR engine  356  also can be provided by a third party. The IR server  355  can be co-located with the ASR server  353 , for example, so that functions of both the first and IR servers can be implemented on a common server platform. The IR server  355  is coupled to the Internet  212  by a signal path  358  that can be wired or wireless. Additionally or alternatively, one or the other or both of the ASR server  353  and the IR server  355  can be communicatively coupled wirelessly to the set top box  202  via an STB antenna  360  and a satellite link. 
         [0059]    The automated customer support system  250  may communicate with a health server that proactively monitors the health of the subscriber&#39;s installed equipment and stores associated equipment health data in a system health database. The health data pertains to relevant pieces of the content receiver system  200 . Upon recognizing potential weak points or breaking points in the system, the automated customer support system carries out the repair of such items prior to the content receiver system  200  going out of service, or notifies the subscriber  224  to take certain steps to avoid the components from going out of service so that they are replaced and repaired without an interruption to the subscriber&#39;s  224  service. Accordingly, the health server may monitor components of the content receiver system  200 , continuously evaluate their health and performance, and store maintenance and system health records in the health server database. Such a database is described further in U.S. patent application No. 14/185,723. 
         [0060]      FIG. 4  shows a sequence of steps in a method  400  of providing automated customer service, according to one embodiment.  FIG. 5  illustrates the user&#39;s experience while requesting and receiving the automated customer service. The method  400  is performed by the automated customer service system  250 . Steps shown on the left side of  FIG. 4  are performed locally by subscriber equipment. Steps shown on the right side of  FIG. 4  are performed by the ASR server  353  or the IR server  355 , or both. Thus, steps shown on the right side of  FIG. 4  may be performed either locally or remotely. 
         [0061]    At  402 , a user, e.g., the television subscriber  224 , activates a voice command function causing the ACS system  250  to receive a spoken user query via the microphone  351  on the remote control  226 . The voice command function can be activated, for example, by a push button, by depressing and holding a “push-to-talk” button on the remote control  226 , by speaking a certain trigger command into the microphone  351 , or by any other method of alerting the ACS system  250  to receive the spoken user query. Speaking directly into the remote control  226  may be more convenient for a subscriber who, for example, may only have access to a land line nearby which is not in the same room as the content receiver system  200 , or who has left their mobile phone elsewhere. On the other hand, in one embodiment, a mobile phone or smart phone can be configured for use as the remote control  226 , as shown in  FIG. 5 , in which case the built-in voice control function of the smart phone receives the spoken user query. 
         [0062]    At  404 , the microphone  351  converts the spoken user query to a corresponding voice data query and the remote control  226  transmits the voice data query to the set top box  202 . Examples of a spoken user query include, “Channel 2 is not working,” “I can&#39;t see any video,” or “Please add channel 100 to my subscription.” Viewers can also be prompted to offer feedback, in response to a video prompt, for example. A viewer may be prompted, for example, to report any errors in the electronic program guide data, which is maintained by content providers. The viewer can then answer such a prompt using the voice-based ACS system  250 . An exemplary exchange between the viewer and the ACS system  250  via the display  204  is shown in  FIG. 5 . 
         [0063]    At  406 , the set top box  202  buffers the voice data and when a complete query is received, forwards the voice data query to the ASR server  353  for processing by the ASR engine  354 . The ASR server  353  can be located remotely, and can be accessed via the existing worldwide communication infrastructure, e.g., via the Internet, satellite communication networks, and the like. The automatic speech recognition engine  354  is implemented, for example, as a set of instructions that cause a microprocessor within the ASR server  353  to interpret the voice data query once it is received by the ASR server  353 . When the Internet connection is broken, regardless of the content of the voice data query, a timeout error will be received when the STB attempts to forward the voice data query to the ASR engine  354 . In response to the timeout error, the STB will advance to step  424  and present an update to the subscriber on the display  204  acknowledging the lack of Internet connectivity and providing instructions to the user for restoring the network connection. Additionally or alternatively, the STB can initiate a hardware or software re-set to reestablish the Internet connection. 
         [0064]    At  408 , the ASR engine  354  performs voice recognition on the voice data query and converts the voice data query to a text query. 
         [0065]    At  410 , the ACS server  353  returns the text query to the set top box  202  for presentation on the display  204 . 
         [0066]    At  412 , the set top box  202  presents the text query on the display  204  so that the subscriber  224  can view the query and verify that their request has been received and interpreted correctly. The set top box  202  can optionally request verification from the subscriber  224 , for example, via a yes/no remote control selection of choices presented on the display  204 . Without subscriber verification, errors in voice recognition may result in a wrong response, or no response, from the ACS system  250 . 
         [0067]    At  414 , in response to a subscriber verification signal, the set top box  202  transmits the text query to the IR server  355  for processing by the IR engine  356 . 
         [0068]    At  416 , the IR engine  356  interprets the text query and decides whether or not the query is within the context of inquiries that can be supported by the set top box. For example, in one embodiment, when the text query contains the words, “not” and “channel 2” the IR engine  356  will decide that the text query is within the context of supportable queries and will continue to execute the method  400 . However, when the text query contains, for example, a random phrase unrelated to television viewing, the IR engine  356  will conclude that the query is not within the proper context for offering a solution to the subscriber  224 . 
         [0069]    At  418 , the IR engine  356  locates a response command corresponding to the text query. When it has been determined at step  416  that the query is not contextual, the IR engine  356  will locate an appropriate response command to communicate a message to the subscriber  224 , such as, for example, “Your query is not supported by subscriber customer service.” Otherwise, the IR engine  356  may locate the response command in a data repository associated with the IR server  355 . The response command is one of a plurality of commands that can be carried out by the set top box  202  or the subscriber  224 . Examples of response commands include changing a setting internal to the set top box  202 , changing a setting internal to the DVR  220 , and communicating information or instructions to the subscriber  224  via the display  204 . Subscriber instructions can include, for example, “Please replace your remote control battery” or, “Snow is blocking your satellite antenna from receiving a full-strength signal,” or “Your subscription plan does not include the selected channel,” as shown in  FIG. 5 . 
         [0070]    Locating an appropriate response command entails at least searching a database of queries and associated response commands and identifying a response command that matches the query. Locating an appropriate response command may further entail consulting a separate database that stores information about the subscriber equipment. For example, the status of certain electrical components may be measured locally and transmitted by the set top box  202  to an equipment health database administered by the television service provider that makes information available to the IR engine  356 . Additionally or alternatively, location of the response command may entail consulting a database that stores information about current weather conditions at the subscriber&#39;s location that may affect operation of the satellite receiving antenna  206 . Additionally or alternatively, locating a response command may entail consulting a database that stores subscriber billing information, subscription plans, promotional offers, and the like. Furthermore, more than one response command can be identified in response to a single query. 
         [0071]    At  420 , the IR engine  356  transmits the response command(s), via the signal path  358 , to the set top box  202  for execution. 
         [0072]    At  422 , the set top box  202  executes the response command. For example, if a response command is in the form of communicating information or instructions to the subscriber  224 , execution entails presenting the instructions on the display  204 , whereas if a response command involves re-setting subscriber equipment, execution by the set top box  202  entails changing internal equipment settings or communicating a signal to another subscriber device to change its internal settings. For example, in response to the query, “I can&#39;t see any video,” the response command identified may cause the STB to switch video inputs automatically. Switching video inputs can be executed by a set top box that is programmed to re-route video input signals, thereby effectively modifying the STB hardware configuration without requiring the user to unplug and re-plug the physical video inputs to the STB. Other response commands may cause the STB to re-set the satellite dish orientation or re-set the satellite signal to a different frequency without the user having to navigate through half a dozen menus to perform the re-set manually. If a response command is not located, the IR engine  356  can be programmed to issue a default response command that re-boots the STB. 
         [0073]    Additionally or alternatively, the response command may entail modifying a subscription plan, for example, if the subscriber  224  decides they want to upgrade their plan instantly to include more channels. 
         [0074]    At  424 , the set top box  202  communicates an update to the subscriber  224  via the display  204 . An example of such an update is a text message reporting that a setting on the subscriber equipment has changed, or that a subscription plan has changed. For example, the set top box  202  may communicate to the user, “The video input has been switched. Can you see the video now?” Multiple response commands can be executed by the set top box substantially simultaneously or in succession, for example, instructions for the subscriber  224  can be presented on the display  204  while the set top box is changing an internal setting. 
         [0075]    The health server  254  may provide additional data to the automated customer service system  250  as described below. Furthermore, information from the health server database may be used to tailor an automated response to a spoken user query, as described herein. When the subscriber  224  initiates a query about his particular content receiver system  200 , the automated customer service system  250 , upon identifying the customer, will then be routed to that particular subscriber&#39;s equipment health status as stored in the database and provided by the health server  254 . The automated customer service system  250  will therefore first provide to the subscriber  224  those questions or data which directly relate to the most vulnerable parts of the system for which the health server  254  has reported potential problems. Rather than having to respond to a large number of interactive computer voice messages, the subscriber will be provided with information concerning parts of his system that are vulnerable to disruption or in need of repair, and to more quickly remedy his situation. This will be a significant benefit to the subscriber  224  because queries in which a computer is responding to the caller&#39;s voice will be tailored to those points of most interest to the health of the equipment installed in his home. The automated customer service system  250  can therefore assist the subscriber  224  in solving the problem without having to transfer the telephone call to the call center and thus take the time of a customer service representative. 
         [0076]    Further, since the automated customer service system  250  has been loaded in advance with the specific health history of the subscriber  224 &#39;s equipment, if, after the initial queries to the subscriber  224  regarding the operation of this system, the automated customer service system  250  concludes that a customer service representative is needed, the transfer can occur very quickly, after just one or two interactions with the subscriber  224 . This will therefore provide a quicker customer response for each customer. In the event the response cannot be immediately provided via the computer system, the subscriber  224  is quickly transferred to a human customer service representative who is able to look at the health history via his computer system and display monitor, since he will have full access to the database associated with the health server  254 , as well as the interaction with the automated customer service system  250 , and thus can immediately help the subscriber  224  solve the problem.
