摘要：
According to this invention, a stereo voice transmission apparatus for coding and decoding voice signals input from a plurality of input units includes a discriminating means for discriminating a single utterance mode from a multiple simultaneous utterance mode, a first coding means for coding the voice signal when the discriminating means discriminates the single utterance mode, a first decoding means for decoding voice information coded by the first coding means, a plurality of second coding means, arranged in correspondence with the plurality of input units, for coding the voice signals when the discriminating means discriminates the multiple simultaneous utterance mode, and a plurality of second decoding means, arranged in correspondence with the plurality of second coding means, for decoding pieces of voice information respectively coded by the plurality of second coding means.
