PROBLEM TO BE SOLVED: To make utterance contents clear and to allow an opposite party to perceive a sense of localization and a sense of distance of a talker in the system where a plurality of units each having a plurality of microphones on a line are arranged to each conference room in a communication conference, a voice of the talker is mainly picked up by one microphone placed near the talker, each microphone signal is corrected and the signals of the respective microphones of each unit are summed as one channel, the result is fed to other conference room, in which the signal is distributed to a plurality of parts, they are corrected respectively and the corrected signals are reproduced for each channel by a plurality of the speakers arranged on a line. SOLUTION: The convolution g (t)*h<-1> (t) is applied as the correction to the sound pickup output of a microphone Mia by using a transfer characteristic h (t) between a talker 11 and the microphone Mia, and a transfer characteristic g (t) between the talker 11 and the position of an image 3 of the talker 11 formed by a video camera, displayed on a screen 2 of a ground system (b), and imagined by a sound pick-up system (a). |
