Abstract
PURPOSE:To execute a simultaneous conversation among three persons without using a conference trunk, by respectively providing switches on the input side of two adders and synthesizing the voice signal of the B channel of an opponent to the sound of a self-voice. CONSTITUTION:Switches 25 and 26 are respectively provided on the input side of a first adder 22 and a second adder 23 and a third adder 24 is added to analog-synthesize sound data received from the receiving part of a first channel and sound data received from the receiving part of a second channel. Thus, the second data received by the second channel can be sent to the transmission part of the first channel together with the sound data of the self-voice and the received sound data of the first channel can be sent to the transmission part of the second channel together with the self-sound data simultaneously. The received sound data from the first channel and the received sound data from the second channel can be simultaneously listened.
