(A-1) Configuration of the First Embodiment FIG. 1 is a block diagram showing the overall configuration of the telephone communication system 1 of this embodiment.

  In the telephone communication system 1, four telephone terminals 20, 30, 40, 50 are connected to the IP network N in FIG. It is assumed that voice data is transmitted between telephone terminals in a packet (hereinafter referred to as “RTP packet”) in the format of RTP (Real-time Transport Protocol; see IETF RFC1889).

  The telephone terminal 20 is a telephone terminal connected to the IP network N and has a call processing device 21. The telephone terminal 20 is connected to the telephone terminals 30 to 50 and provides a telephone conference with the user of each telephone terminal. Although not shown in FIG. 1, the telephone terminal 20 is assumed to have other configurations such as a speaker and a microphone that the telephone terminal has.

  The call processing device 31 has a function of performing processing related to a call such as a conference call in the telephone terminal 20, and includes a telephone function unit 22, a conference function unit 23, and a voice data processing device 24. .

  The call processing device 31 may be mounted on a telephone terminal, or may be realized on an information processing device such as a personal computer constructed as a soft phone.

  The telephone function unit 22 has a function of performing a voice call in the call processing device 21.

  The conference function unit 23 has a function of providing a conference function (for example, session management with a telephone terminal participating in a conference) for making a call simultaneously with a plurality of call partners (telephone terminals 30 to 50) in the call processing device 21. I'm in charge. The conference function unit 23 can apply the same function as the conference function in the existing conference call system.

  FIG. 2 is a block diagram showing a functional configuration inside the audio data processing device 24.

  The audio data processing device 24 is an information processing device having a program execution configuration such as a CPU, ROM, RAM, EEPROM, hard disk, etc. (not limited to one, but may be a device that can process a plurality of devices in a distributed manner. In addition, it is constructed by installing the audio data processing program or the like of the embodiment, and can be functionally shown as in FIG. 2 described above. For example, when the telephone terminal 20 is realized on an information processing device such as a personal computer, the voice data processing device 24 is also constructed by installing the voice data processing program or the like of the embodiment on the information processing device. You may do it.

  The voice data processing device 24 mixes voice data of RTP packets received from a plurality of call partners (telephone terminals 30 to 50) by designating the volume for each caller, synthesizes it into one voice data, and outputs it. It has a control unit 243, a volume control unit 244, and a packet processing unit 245 (245-1 to 245-3).

  The UDP / IP control unit 246 has a function of a general-purpose socket that receives RTP packets.

  The packet processing unit 245 (245-1 to 245-3) performs processing such as buffering and transmission source analysis on the RTP packet received by the UDP / IP control unit 246. The packet analysis unit 245a (245a) -1 to 245a-3) and buffer portion 245b (245b-1 to 245b-3).

  In the voice data processing device 24, the packet processing unit 245 is arranged for each communication partner, and there are three communication terminals, the telephone terminals 30 to 50. Therefore, in FIG. 1 to 245-3 are arranged. In the audio data processing device 24, the number of packet processing units 245 may be fixed or dynamically changed. For example, each packet processing unit 245 may be generated as one thread on the program, and the number of threads may be dynamically changed. In this embodiment, description will be made assuming that when the UDP / IP control unit 246 receives an RTP (Real-time Transport Protocol) packet, a thread of the packet processing unit 245 is generated for each transmission source of the packet. Further, in the audio data processing device 24, a plurality of packet processing units 245 may be arranged in advance and used as many as the number of communication partners. As described above, in the audio data processing device 24, the arrangement (generation) and management method of the packet processing unit 245 are not limited.

  When receiving RTP packets, the buffer units 245b-1 to 245b-3 absorb delay and fluctuation peculiar to VoIP for each partner and supply the RTP packets to the packet analysis units 245a-1 to 245a-3. It plays the role of a jitter buffer.

  The packet analysis units 245a-1 to 245a-3 analyze the transmission source of the RTP packets given from the buffer units 245b-1 to 245b-3. In this embodiment, as an example, the packet analysis units 245a-1 to 245a-3 analyze the transmission source by extracting the transmission source IP address as information related to the transmission source from the header information of the RTP packet. Then, the packet analysis units 245a-1 to 245a-3 give the RTP packet and the transmission source IP address extracted from the RTP packet as a set to the volume control unit 244. In the following description, the IP address of the telephone terminal 30 is A, the IP address of the telephone terminal 40 is B, and the IP address of the telephone terminal 50 is C.

  The control unit 243 has an interface for volume adjustment with the higher-level function units (telephone function unit 22, conference function unit 23, etc.), and holds information relating to the other party (several) who are currently talking. And a volume control designation unit 243a.

  In the volume control designation unit 243a, the identification information of the other party's telephone terminal currently connected to the conference call and the volume value for each destination telephone terminal (hereinafter referred to as “designated volume value”) are supported in the telephone terminal 20. Add and register. As the designated volume value, for example, a specific volume value such as 10 db or 20 db may be set, or a coefficient such as 1, 2, 3,... May be set. Description will be made assuming that the coefficient is set. Further, in the volume control designation unit 243a, for example, a default value may be set in advance as the designated volume value, and the designated volume value may be raised or lowered from the default value according to a user operation.

  The designated volume value set in the volume control designation unit 243a may be a preset content or may be changed according to a user operation. For example, the telephone terminal 20 is provided with a button for raising or lowering the designated volume value for each telephone terminal (IP address) of the destination of the conference call, or with a numeric keypad for setting the designated volume value. Alternatively, when the call processing device 21 is realized on an information processing device such as a personal computer constructed as a soft phone, a mouse operation or key operation on the information processing device (personal computer) The user may be allowed to input a designated volume value for each telephone terminal (IP address) of the other party of the conference call, and the configuration for allowing the user to input the designated volume value is not limited. Further, the designated volume value set in the volume control designation unit 243a may be changed according to the user's operation while the telephone terminal 20 is connected to the telephone conference.

  In the volume control designation unit 243a, the identification information related to the telephone terminal of the destination to be set is, for example, set (connected) in a telephone conference in a higher-level function unit (telephone function unit 22, conference function unit 23, etc.). It may be extracted from the session information applied at the time of application.

  The volume control unit 244 performs volume control processing on the RTP packets given from the packet processing units 245-1 to 245-3, and includes a gain adjustment unit 244a and a packet control unit 244b.

The designated volume value is inserted into the RTP packet and given to the gain adjusting unit 244a.

  As shown in FIG. 3, when the RTP packet paired with the source IP address is given from the packet analysis units 245a-1 to 245a-3, the packet control unit 244b is registered in the volume control designation unit 243a. The designated volume value corresponding to the transmission source IP address is searched from the received information, and the designated volume value is inserted into the RTP packet.

  FIG. 4 is an explanatory diagram showing processing of the gain adjusting unit 244a and the mixing unit 242.

  As shown in FIG. 4, the gain adjusting unit 244a extracts voice data (for example, PCM data) from the RTP packet given from the packet control unit 244b, and further determines the volume of the voice data to the packet control unit 244b. The volume is changed to the volume specified by the specified volume value inserted by (Gain adjustment), and is given to the mixing unit 242. Gain adjusting section 244a adjusts the volume of audio data related to an RTP packet having a larger specified volume value inserted in the RTP packet. For example, the gain adjusting unit 244a adjusts so that the sound data of the RTP packet with the designated sound volume value 3 is louder than the sound data of the RTP packet with the designated sound volume value 1.

  For example, when a coefficient such as 1, 2, 3,... Is assigned as the designated sound volume value, the gain adjusting unit 244a has 10 db when the designated sound volume value is 1, 20 db when the designated sound volume value is 2, and the like. The volume corresponding to the coefficient may be set in advance in the Gain adjusting unit 244a, and the volume of the audio data may be adjusted to the corresponding volume.

  Further, the gain adjusting unit 244a may set the volume of the audio data at a volume ratio according to the specified volume value, for example. For example, the specified volume value of the RTP packet of the source IP address A is 2, the volume value after gain adjustment is X, the specified volume value of the source IP address B is 1, the volume value after gain adjustment is Y, and the source IP When the designated volume value of the address C is 1 and the volume value after Gain adjustment is Z, the volume ratio of X, Y, and Z is adjusted to be 2: 1: 1. .

  As shown in FIG. 4, when the audio data for each IP address of the transmission source is given from the gain adjusting unit 244a, the mixing unit 242 mixes (combines) the audio data into one audio data, and outputs the sound. Part 241. In the mixing unit 242, as a method of synthesizing a plurality of voice data, for example, in a method of synthesizing existing PCM data or a conference call system using existing VoIP, a voice from a plurality of telephone terminals is synthesized. Methods etc. can be applied.

  The sound output unit 241 outputs the audio data given from the mixing unit 242 using an audio output device (speaker).

(A-2) Operation of the First Embodiment Next, the overall operation (voice data processing method of the embodiment) of the telephone communication system 1 of the first embodiment having the above configuration will be described.

  FIG. 5 is a flowchart illustrating the operation of the call processing device 21 in the telephone communication system 1.

  In the description of FIG. 5, it is assumed that in the audio data processing device 24, three packet processing units 245-1 to 245-3 (threads thereof) are generated under the control of the UDP / IP control unit 246. The packet processing unit 245-1 is generated for the telephone terminal 30, the packet processing unit 245-2 is generated for the telephone terminal 40, and the packet processing unit 245-3 is the telephone terminal. A description will be given on the assumption that the data is generated for 50.

  First, when the RTP packet is received from the other telephone terminals 30 to 50 by the UDP / IP control unit 246 (S101), the RTP packet is given to the buffer units 245b-1 to 245b-3, and the buffer units 245b-1 to 245b- 3, when a certain amount of RTP packets are buffered, the packet analyzers 245a-1 to 245a-3 analyze the source IP addresses of the RTP packets (S102).

  Then, in the packet control unit 244b, the packet analysis units 245a-1 to 245a-3 perform analysis for each IP address of the transmission source on the basis of the volume designation value set in the control unit 243 (volume control designation unit 243a). The designated volume value is inserted into the RTP packet that has been sent (S103).

  Then, the gain adjusting unit 244a extracts voice data from the RTP packet in which the designated volume value is inserted by the packet control unit 244b, and adjusts the volume according to the designated volume value (S104).

  The mixing unit 242 mixes (synthesizes) the audio data whose volume has been adjusted by the gain adjusting unit 244a with the volume ratio adjusted by the gain adjusting unit 244a, and generates mixed audio data ( S105).

  Then, the audio data mixed by the mixing unit 242 is converted into an appropriate output format by the sound output unit 241 (S106), and is output by the speaker of the telephone terminal 20.

(A-3) Effects of First Embodiment According to the first embodiment, the following effects can be achieved.

  In the audio data processing device, the larger the designated volume value is set, the higher the volume is mixed, so that the voice of a specific destination can be output clearly. In particular, when the background noise level differs for each partner, it may be necessary to reduce the voice of the partner having a large background noise.

  Also, the packet control unit inserts information on the designated volume value corresponding to the transmission source IP address into each RTP packet, and the gain adjustment unit adjusts the volume of the audio data based on the inserted designated volume value. is doing. Thus, not only a conference call in which a plurality of speakers speak in turn, such as PoC, but also a conference call in which a speaker at a plurality of phone terminals speaks simultaneously, The amount of sound can be controlled according to the user's operation.
