ある。 In conventional audio teleconferencing systems, speakers in various locations speak through microphones and listen to what the other party is saying through speakers to conduct a conference. In this case, the line used between the conference partner and the other party is a single line using the audio frequency band (0.3kHz to 3.4kHz), so it is an auditory communication using only voice, and if the speaker is an unfamiliar person, it may be misidentified. However, it has the disadvantage of reducing the reliability of the meeting.

であることが判る。 For example, when a speaker assigned to the microphone 11 of station A speaks, it is detected by the voice input detection circuit 21 and this detection signal is input to the data transmission circuit 26. At this time, data sending circuit 2
6 starts. However, the audio input detection circuit 22-2
4, no audio input is detected, so the detection signal is not input to the data sending circuit 26. Therefore, the data sending circuit 26 recognizes the voice input detection circuit 21 side as "1" and the voice input detection circuits 22 to 24 side as "0", for example. Therefore, this parallel signal of "1", "0", "0", "0" is made into a serial signal, attached with the code number of the own station, and transmitted to the coupling device 27 by the modulator 28 on a carrier wave of, for example, 3315 Hz. On the other hand, the audio signal from the microphone 11 is transmitted to a coupling device 27 via an audio amplifier 25.
sent to. The coupling device 27 consists of, for example, a 3315Hz band waver and a 3100Hz low band waver,
The voice passes through the low frequency device and the speaker identification information is 3315
The signal is frequency-division multiplexed through the Hz band wave generator and transmitted to the receiving section of the "B" station via the transmission line 30. In the receiving section of the B station, this signal is sent to the separating circuit 51, and the speaker identification information is 3315 as in the combining circuit 27.
The audio passes through a 3100Hz bandpass filter, and then the audio passes through a 3100Hz lowpass box and is separated. The audio is broadcast into station B via a speaker 55 via an audio amplifier 52. On the other hand, the speaker identification information is demodulated by the demodulator 54 using a carrier wave of 3315 Hz and inputted to the data output circuit 53. The data output circuit 53 detects the code number of the station string and also detects the transmitted "1""0""0""0" signal and uses this as parallel data for the A station of the speaker identification display device 56. to the display circuit. As a result, in the speaker identification display device 56, the display device for station A, for example, a light emitting diode, emits light only at the "1" signal. This shows that the speaker who is currently speaking is the one to whom the microphone 11 of station A has been assigned.
上記説明の結合装置２７分離装置５１で音声を
3100Hzの低域波器でカツトする如くしてあるが
これによつては音質には影響はない。 The audio is output by the combining device 27 and the separating device 51 described above.
A 3100Hz low frequency filter is used to cut the sound, but this does not affect the sound quality.

も拡大する。 As explained in detail above, according to the present invention, the speaker identification information for each station is transmitted to the ground station and the speaker for each station is displayed on the speaker identification display device of each ground station, so visual information is added and the speaker Since the reliability of the audio teleconferencing system can be understood, the reliability of the audio teleconferencing system can be improved and the range of use can be expanded.
