(Step SB3). In this case, the voice of participant A and the voice of participant C are output from the speaker of information processing apparatus 10C. When only the audio signal including the participant identifier of the participant 2C is received, the information processing apparatus 10C stops supplying the audio signal to the speaker (step SB4).

  When the participant identifier of the participant who is in the same room is stored in the storage unit 102 (YES in step SB1), the information processing device 10 uses the participant identifier included in the received audio signal. It is determined whether there is a participant identifier other than the participant identifier to be transmitted and the participant identifier stored in the storage unit 102 (step SB5). When the participant identifier included in the received audio signal includes a participant identifier other than the participant identifier transmitted by the information processing device 10 and the participant identifier stored in the storage unit 102 (step S110). (YES in SB5), the audio signal transmitted from the server device 20 is converted into an analog audio signal, and the analog audio signal is supplied to the speaker (step SB6).

  For example, when only the audio signal transmitted by the information processing apparatus 10C is received, the information processing apparatus 10A converts the received audio signal into an analog audio signal and supplies the analog audio signal to the speaker (step SB6). In this case, the voice of the participant C is output from the speaker of the information processing apparatus 10A. When the information processing apparatus 10A receives the audio signal transmitted by itself, in addition to the audio signal transmitted by the information processing apparatus 10C, the information processing apparatus 10A converts the received audio signal into an analog audio signal and supplies the analog audio signal to the speaker (step SB6). . In this case, the voice of participant A and the voice of participant C are output from the speaker of information processing apparatus 10A.

  When only the audio signal transmitted by the information processing apparatus 10C is received, the information processing apparatus 10B converts the received audio signal into an analog audio signal and supplies the analog audio signal to the speaker (step SB6). In this case, the voice of the participant C is output from the speaker of the information processing apparatus 10B. When the information processing apparatus 10B receives the audio signal transmitted by the information processing apparatus 10A in addition to the audio signal transmitted by the information processing apparatus 10C, the information processing apparatus 10B converts the received audio signal into an analog audio signal and supplies it to the speaker ( Step SB6). In this case, the voice of participant A and the voice of participant C are output from the speaker of information processing apparatus 10B.

  In the information processing apparatus 10, the participant identifier of the participant in the same room is stored in the storage unit 102 (YES in step SB1), and the own apparatus transmits the participant identifier included in the received audio signal. If there is no participant identifier other than the participant identifier and the participant identifier stored in the storage unit 102 (NO in step SB5), that is, from the information processing apparatus 10 in another room in the received audio signal If there is no transmitted audio signal, supply of the audio signal to the speaker is stopped (step SB7).

  For example, when the information processing apparatus 10A receives only the audio signal transmitted by the information processing apparatus 10B, or when the audio signal transmitted by the information processing apparatus 10A is received in addition to the audio signal transmitted by the information processing apparatus 10B, The supply of the audio signal to the speaker is stopped (step SB7). Further, when the information processing apparatus 10B receives only the audio signal transmitted by the information processing apparatus 10A, or when the audio signal transmitted by the information processing apparatus 10A is received in addition to the audio signal transmitted by the information processing apparatus 10B, The supply of the audio signal to the speaker is stopped (step SB7).
