ABSTRACT:
A voice communication apparatus in which voice and voiceless parts are detected from voice signal data which is derived from analog-to-digital converted input voice signal, the voice signal data is temporarily stored in a transmitting buffer in a time series manner so that, when a voice part is detected, transmission of the voice signal data stored in the transmitting buffer is started from a voice start point of the voice part preceding a voice detection point, whereby a head part truncation, which would occur at the time of shifting from the voiceless part to the voice part can be eliminated and thus a high quality of natural speech communication can be realized.
