  • memory means for sequentially storing the data blocks;

    voice/silence detecting means for detecting voice presence and absence parts in said voice signal; and

    transmission means for transmitting, on a burst basis, a predetermined number of data blocks stored in said memory means prior to detection by said voice/silence detecting means of a change in the voice signal from the voice absence part to the voice presence part.
