PURPOSE:To increase the reliability of an audio remote control conference system and to increase the range of application of said system, by transmitting the speaker identification information of each station to a ground station and then displaying the speaker. CONSTITUTION:The detection signal of the speaker voice of a station A is processed by a data feeding circuit 26. The identification signal of the circuit 26, the modulated 28 signal of the code number of the own station and the speaker identification information given from an amplifier 25 are multiplexed 27 with division of frequency and then transmitted. At a station B, the separated 51 speaker identification information is fed to a data output circuit 53 via a demodulator 54. The code number of each station and the identification signal are detected and fed to a display circuit for station A of a speaker identification display device 56 in the form of a parallel data. Thus the corresponding LED emits the light, and the speaker of the station A is identified. |
