PURPOSE: To provide a communication conference terminal equipment capable of efficiently operating a communication conference in which plural members participate. CONSTITUTION: The gain of variable gain amplifiers 32, 35 and 37 for amplifying voice signals larger than a prescribed level among the voice signals inputted from plural microphones 2-4 is set at a large value. Thus, the voice signals of a main speaker are emphasized and the voice of the main speaker is clearly listened to in an opposite terminal. Also, since the signals of a non voice band included in signals inputted from the microphones 2-4 are removed in a low-pass filter 39, the clear voice from which noise other than the voice is suppressed is obtained in the opposite terminal. |
