CA 2259071

A voice encoding/decoding apparatus includes a voice encoding unit and a voice decoding unit. In the voice encoding unit, a non-voice signal detector detects whether an input signal is a voice signal or a non-voice signal and outputs a signal identification signal on the basis of the detection result. When the non-voice signal detector detects a voice signal, a voice encoder encodes the input signal as the voice signal and transmits encoded data to the voice decoding unit. When the non-voice signal detector detects a non-voice signal, the voice encoding unit transmits the input signal to the voice decoding unit as non-encoded transmission data. The voice decoding unit includes a voice decoder and a first switch. When the non-voice signal detector detects the voice signal, the voice decoder decodes the encoded data transmitted from the voice encoder and outputs the decoded voice signal. The first switch selects, on the basis of the signal identification signal output from the non-voice signal detector, the decoded voice signal or the non-encoded transmission data.
