Abstract of the Disclosure On the transmission side, speech signals of a plurality of channels are multiplexed by a pulse code modula- tion system, a partial autocorrelation coefficient and an excitation signal which constitute a feature parameter of the speech are extracted from the multiplexed signals by means of a speech analyzer for respective digital outputs correspond- ing to respective speech signals, and the extracted feature parameter is multiplexed again and then transmitted to the receiving side. On the receiving side, the received multi- plexed signal of the feature parameter is applied to a speech synthesizer on a time division basis for reproducing a multiplex pulse code modulation signal of the speech wave, and the reproduced signal is distributed among respective channels.
