The HDD 64 stores a program for causing the CPU 60 to execute a call recording process (see FIG. 7) and a data providing process (see FIG. 9). The HDD 64 stores search data and call data. The call data is voice data that records a voice call made in one call.

  With reference to FIG. 4 to FIG. 11, relay processing (particularly, processing executed by the router 10 and the server 6) executed at the time of a voice call in the communication system 1 will be described. In the following description, a terminal device that is a call originator is referred to as a calling terminal, and a terminal device that is a call receiver is referred to as a called terminal.

  The relay process of the router 10 will be described with reference to FIG. This relay processing is continuously executed by the CPU 11 based on a program stored in the ROM 12 until the router 10 is turned off.

  In the relay process of the router 10, it is first determined whether or not the call is started (S1). In step S1, when a call signal requesting telephone connection is received from the calling side terminal, it is determined that the call is started (S1: YES). In this case, it is determined whether or not the call is an emergency call based on the type of voice call indicated by the call signal received in step S1 (S3). An emergency call is a voice call made with a predetermined emergency contact (for example, police, fire department, hospital, etc.). In the present embodiment, an address table in which telephone numbers of emergency contacts are registered is recorded in the flash memory 14. In step S3, when the telephone number requested by the call signal as a connection destination is registered in the address table, it is determined that the type of the voice call indicated by the call signal is an emergency call. In an emergency call, a direct call is made without going through the server 6 so that a call can be made even if the server 6 is down. The details will be described later.

  When it is determined that the call is not an emergency call (that is, a normal call) (S3: NO), a normal call process described later is executed (S5). When it is determined that the call is an emergency call (S3: YES), an emergency call process described later is executed (S7). After execution of step S5 or step S7, that is, after completion of the normal call or emergency call, search data described later is received from the server 6 (S9) and stored in the flash memory 14 (S11). After execution of step S11 or when the call is not started (S1: NO), the process returns to step S1.

  The normal call process (S5) will be described with reference to FIG. In the normal call process, first, the server 6 is notified of the start of the call (S21). The call start notification is a signal for instructing the start of a normal telephone call, and includes data indicating a communication method (for example, analog, IP, etc.) executed during the normal telephone call. After execution of step S21, analog voice is received from the calling terminal (S23) and digitally converted (S25). The data (digital audio) converted in step S25 is transmitted to the server 6 (S27). Thereafter, digital audio is received from the server 6 (S29) and converted to analog (S31). The data (analog voice) converted in step S31 is transmitted to the called terminal (S33).

  That is, in steps S23 to S33, the user's voice (that is, analog voice) acquired by the microphone (not shown) of the calling terminal is converted into digital voice and transferred to the server 6. Thereafter, the digital voice returned from the server 6 is converted into analog voice and transferred to the called terminal. In the called terminal, the analog voice (such as the voice of the user of the calling terminal) received from the router 10 is output from a speaker (not shown).

  After execution of step S33, analog voice is received from the called terminal (S35) and digitally converted by a known method (S37). The data (digital sound) converted in step S37 is transmitted to the server 6 (S39). Thereafter, digital audio is received from the server 6 (S41) and converted into an analog signal by a known method (S43). The data (analog voice) converted in step S43 is transmitted to the calling terminal (S45).

  That is, in steps S35 to S45, the user's voice (that is, analog voice) acquired by the microphone (not shown) of the called terminal is converted into digital voice and transferred to the server 6. Thereafter, the digital voice returned from the server 6 is converted to analog voice and transferred to the calling terminal. In the calling terminal, analog voice (such as the voice of the user of the called terminal) received from the router 10 is output from a speaker (not shown).

  After execution of step S45, it is determined whether or not the call has ended (S47). If the call has not ended (S47: NO), the process returns to step S23. Thereby, steps S23 to S45 are repeatedly executed while the voice call is continued. When the call ends (S47: YES), the end of the call is notified to the server 6 (S49). The call end notification is a signal for instructing the end of a normal call. After execution of step S49, the process returns to the relay process (FIG. 4).

  The emergency call process (S7) will be described with reference to FIG. In the emergency call process, first, analog voice is received from the calling terminal (S51) and converted into digital data (S53). The data (digital sound) converted in step S53 is stored in the flash memory 14 (S55). The analog voice acquired in step S51 is transmitted to the called terminal (S37). That is, in steps S51 to S57, the user's voice or the like (that is, analog voice) acquired by the microphone (not shown) of the calling terminal is converted into digital voice and stored in the flash memory 14, while the conversion is performed. The previous analog voice is transferred to the called terminal. In the called terminal, the analog voice (such as the voice of the user of the calling terminal) received from the router 10 is output from a speaker (not shown).

  After execution of step S57, analog voice is received from the called terminal (S59) and digitally converted (S61). The data (digital audio) converted in step S61 is stored in the flash memory 14 (S63). The analog voice acquired in step S59 is transmitted to the calling terminal (S65). That is, in steps S59 to S65, the user's voice or the like (that is, analog voice) acquired by the microphone (not shown) of the called terminal is converted into digital voice and stored in the flash memory 14, while the conversion is performed. The previous analog voice is transferred to the calling terminal. In the calling terminal, analog voice (such as the voice of the user of the called terminal) received from the router 10 is output from a speaker (not shown).

  After execution of step S65, it is determined whether or not the call has ended (S67). If the call has not ended (S67: NO), the process returns to step S51. Thereby, steps S51 to S65 are repeatedly executed while the voice call is continued. When the call is finished (S67: YES), the emergency telephone registration is notified to the server 6 (S69). The emergency call registration notification is a signal indicating that the emergency call has started and ended (that is, completed), and includes data indicating a communication method executed at the time of the emergency call. Further, a plurality of digital voices stored in the flash memory 14 during an emergency call are transmitted in a batch (S71). Note that the plurality of digital sounds transmitted in a batch in step S71 are deleted from the flash memory 14. After execution of step S71, the process returns to the relay process (FIG. 4).

  The call recording process of the server 6 will be described with reference to FIG. This call recording process is continuously executed by the CPU 61 based on a program stored in the HDD 64 until the server 6 is turned off.

  In the call recording process of the server 6, it is first determined whether or not there is a call start notification from the router 10 (S201). If there is a call start notification (S201: YES), this means that a normal call has started. In this case, digital audio is received from the router 10 (S203) and stored in the HDD 64 (S205). Further, the digital voice received in step S203 is transmitted to the router 10 (S207). That is, in steps S203 to S207, the digital audio transferred from the router 10 during a normal telephone call is stored in the HDD 64 and then returned to the router 10.

  After execution of step S207, it is determined whether or not there is a call end notification (S209). If there is no notification of the end of the call (S209: YES), the process returns to step S203 because the normal call has not ended. If there is a call end notification (S209: YES), it means that the normal call has ended. In this case, a plurality of digital voices stored in the HDD 64 at the time of normal telephone call are synthesized and one call data is generated (S211). Note that the digital voice that is the source of the call data is deleted from the HDD 64.

  On the other hand, if there is no call start notification (S201: NO), it is determined whether there is an emergency call registration notification from the router 10 (S213). If there is a notification of emergency call registration (S213: YES), it means that the emergency call has been completed. In this case, a plurality of digital voices are collectively received from the router 10 (S215) and stored in the HDD 64 (S217). After execution of step S217, call data is generated in the same manner as described above (S211).

  After execution of step S211, voiceprint recognition and text conversion of the call data is executed (S219). In voiceprint recognition, a voiceprint included in call data is recognized by a known voiceprint analysis technique. In the text conversion, the content of the call included in the call data is converted into character information by a known voice recognition technique, and the call text is generated. Search data, which is related information of the call data generated in step S211, is generated (S221).

  Specifically, search data 90 illustrated in FIG. 10 is generated. Although not shown, the search data 90 includes the call text generated in step S219. The transmission date and time, the start time, the end time, and the call record are set based on the time stamp of the digital voice that is the generation source of the search data 90. For the telephone in use, a voice call method indicated by a call start notification or an emergency call registration notification is set. As the subject, the word having the highest number of appearances is set based on the call text generated in step S219. The caller is set with the user name of the calling terminal identified based on the voiceprint recognized in step S219. The recipient is set with the user name of the called terminal identified based on the voiceprint recognized in step S219.

  In the present embodiment, a correspondence table between voiceprints and names (for example, Suzuki, Yamada, etc.) is registered in the HDD 64. If the name corresponding to the voiceprint recognized in step S219 is registered in the HDD 64, the registered name is set as the user name. If the name corresponding to the voiceprint recognized in step S219 is not registered in the HDD 64, or if the voiceprint cannot be recognized correctly, an identification name (for example, A, B, etc.) for specifying the user is set. Automatically given and set as user name.

  The call data generated in step S211 and the search data generated in step S221 are stored in association with the HDD 64 (S223). Further, the search data is transmitted to the router 10 (S225). After execution of step S225 or when there is no notification of emergency call registration (S213: NO), the process returns to step S201.

  For example, when the user “Suzuki” calls the fixed phone 7 of the user “Z” using the extension telephone 2, if the user “Z” is not an emergency contact, the normal call processing is executed in the router 10 (S1). : YES, S3: YES, S5). The server 6 generates and stores call data and search data based on the call voice between the extension telephone 2 and the fixed telephone 7 (S201: YES, S203 to S207, S209: YES, S211, S219 to S223). . The search data generated by the server 6 is also stored in the router 10 (S225, S9, S11).

  On the other hand, if the user “Z” is an emergency contact, an emergency call process is executed in the router 10 (S1: YES, S3: NO, S7). Also in this case, the server 6 generates and stores call data and search data based on the call voice between the extension telephone 2 and the fixed telephone 7 (S201: NO, S213: YES, S215 to S223). The search data generated by the server 6 is also stored in the router 10 (S225, S9, S11).

  The search process of the router 10 will be described with reference to FIG. This search process is continuously executed by the CPU 11 based on a program stored in the ROM 12 until the router 10 is turned off.

  In the search process of the router 10, it is first determined whether or not the search is started (S81). In the present embodiment, when an application (hereinafter referred to as search software) for searching for call data is activated in a terminal device (hereinafter referred to as search terminal) used by a user during a search, the activated search software is transferred to the router 10. Issue an access request. When this access request is received, it is determined that the search is started (S81: YES). In this case, the update confirmation of the search data stored in the router 10 is transmitted to the server 6 (S83). The update confirmation is a signal for instructing whether or not the search data has been updated to the latest one, and includes the generation date and time (latest update date and time) of the search data last received from the server 6.

  After execution of step S83, it is determined whether update data has been received from the server 6 (S85). The update data is data for updating the search data stored in the flash memory 14. When the update data is received (S85: YES), the search data stored in the flash memory 14 is updated based on the update data received in step S85 (S87). After execution of step S87 or when update data has not been received (S85: NO), a search screen is displayed on the search software of the search terminal (S89). Specifically, the search data stored in the flash memory 14 is read and transmitted to the search terminal. In the search terminal, a search screen (see FIG. 10) including the received search data is generated by search software and displayed on a display (not shown).

  The search screen illustrated in FIG. 10 is a voice inbox 100 including a plurality of search data 90 received from the router 10. The voice inbox 100 includes a data display unit 101 in which a plurality of search data 90 are selectably displayed, a search field 102 for performing a keyword search for the plurality of search data 90, and a data display area unit A call content display unit 103 that displays the text of the search data 90 selected in 101. Further, the call content display unit 103 is provided with a voice reproduction button 104 for instructing voice reproduction of the call data corresponding to the search data 90 selected in the data display area unit 101.

  After execution of step S89, it is determined whether there is a search request (S91). Specifically, when a search key is input to the search field 102 of the voice inbox 100 at the search terminal, the search software transmits a search request including the search key to the router 10. When the router 10 receives a search request from the search terminal (S91: YES), the router 10 executes a search process according to the search request (S93). That is, the call text including the word that matches the search key included in the search request is searched for the call text of the search data stored in the flash memory 14. The search result of step S93 is displayed on the search software of the search terminal (S95).

  In the example shown in FIG. 10, when the search key “work” is entered in the search field 102, the call text including the search key “work” is searched from the search data 90 in the flash memory 14 and hit in the router 10. Search data 90 is transmitted to the search terminal. As a result, in the search terminal, a search screen (see FIG. 11) including the received search data is generated by the search software and displayed on the display (not shown). In FIG. 11, a voice inbox 100 indicating that two search data hits the search key “work” is displayed as a search screen.

  After execution of step S95 or when there is no search request (S91: NO), it is determined whether or not there is a voice request (S97). Specifically, when the audio playback button 104 of the audio receiving tray 100 is clicked on the search terminal, the search software transmits an audio request to the router 10. The voice request is a signal for requesting call data corresponding to the search data selected on the search screen. When a voice request is received from the search terminal (S97: YES), a voice search instruction is transmitted to the server 6 (S99). The voice search instruction is a signal for instructing a search for call data requested by a voice request.

  After execution of step S99, call data is received from the server 6 (S101). The search software of the search terminal is caused to reproduce the voice of the call data received in step S101 (S103). Specifically, the call data received in step S101 is transferred to the search terminal. In the search terminal, the received call data is output as audio from a speaker (not shown) by search software.

  After execution of step S103 or when there is no voice request (S91: NO), it is determined whether or not the search is completed (S105). In the present embodiment, when the search software is terminated at the search terminal, the search software issues an end notification to the router 10 when the operation ends. If this end notification is received, it is determined that the search has ended (S105: YES). In this case, the process returns to step S81. If the search is not finished (S105: NO), the process returns to step S89.

  With reference to FIG. 9, the data provision process of the server 6 is demonstrated. This search process is continuously executed by the CPU 11 based on a program stored in the ROM 12 until the router 10 is turned off.

  In the data providing process of the server 6, it is first determined whether or not an update confirmation has been received from the router 10 (S231). When the update confirmation is received (S231: YES), the latest update date and time included in the update confirmation is collated with the generation date and time (latest update date and time) of the latest search data stored in the HDD 64 (S233). Based on the collation result, it is determined whether or not the latest update date and time match (S235). If the latest update date / time does not match (S235: NO), the search data (update data) is insufficient so that the search data stored in the router 10 matches the search data stored in the HDD 64. Is transferred to the router 10 (S237).

  After execution of step S237, it is determined whether or not a voice search instruction has been received from the router 10 (S239). When the update confirmation has not been received (S231: NO), or when the latest update date / time is the same (S235: YES), it is determined whether a voice search instruction has been received (S239). When the voice search instruction is received (S239: YES), the call data indicated by the voice search instruction is searched from the HDD 64 (S241). The call data hit in step S241 is transmitted to the router 10 (S243). After execution of step S243, or when a voice search instruction has not been received (S239: NO), the process returns to step S231.

  For example, when the user activates the search software on the PC 5, the voice reception tray 100 (see FIG. 10) is displayed on the display (not shown) of the PC 5 (S81: YES, S83 to S89). At this time, if the search data 90 stored in the router 10 is not the latest, the search data 90 of the router 10 is updated by data communication with the server 6 (S85: YES, S87, S231: YES). , S233, S235: YES, S237). As described above, when the user operates the voice receiving tray 100, search and reproduction of call data are executed (S91 to S103, S239 to S243).

  As described above, according to the present embodiment, a terminal device capable of making a voice call (for example, the extension telephone 2) and another terminal device (for example, the fixed telephone 7) connected to the IP network 32 or the PSTN 33 are used. In between, the router 10 relays the voice data. The server 6 generates call data and search data based on the voice data relayed by the router 10. The call data is stored in the HDD 64, and the search data is stored in the flash memory 14 and the HDD 64. Therefore, the user can search the corresponding search data from the flash memory 14 or the HDD 64 based on the search key, and can also search the corresponding call data from the HDD 64. That is, it is possible to search for voice data generated during a voice call using an existing terminal device (for example, the extension telephone 2 or the fixed telephone 7).

  Further, the router 10 extracts the search data corresponding to the search key included in the search request transmitted from the search terminal (for example, the PC 5) from the flash memory 14 and transmits it to the search terminal. The router 10 causes the server 6 to extract call data corresponding to the voice request transmitted from the search terminal (for example, the PC 5) from the HDD 64 and transmit the call data to the search terminal. Therefore, the user can acquire call data and search data using the search terminal.

  Further, the router 10 converts analog voice relayed by voice call performed on the analog line into digital voice and causes the server 6 to store it in the HDD 64. Therefore, it is possible to search for voice data generated during a voice call using an analog line.

  Further, when the type of voice call is a normal phone, the router 10 transfers the voice data received from the calling side terminal to the server 6 and then transmits it to the called side terminal. When the type of the voice call is an emergency call, the voice data received from the calling terminal is temporarily stored in the router 10 and transmitted to the called terminal collectively after the call is finished. Therefore, voice data can be recorded in the server 6 in real time during a normal call, while call delay due to recording of voice data can be suppressed during an emergency call.

  The search data is stored in the router 10 (specifically, the flash memory 14 in detail) because the data amount is small. Thereby, the search result of the search data can be quickly provided without inquiring of the server 6 when searching for the search data. On the other hand, since call data has a large amount of data, it is stored in the server 6 (specifically, the HDD 64). As a result, the call data can be provided to the search terminal only when necessary while reducing the burden on the hardware resources of the router 10. Furthermore, by storing the search data in the server 6 (specifically, the HDD 64), the search data stored in the router 10 can be updated as necessary.
