ABSTRACT:
The period of a sound-existence/sound-silence of a speech signal is detected. Packet data is inserted in a speech time slot during the period of non-existence of sound in the speech signal. A time slot is also given to the non-speech data requiring a quick response in transmission so that the non-speech data is multiplexed with the speech signal for transmission. Data-non-existence of non-speech data is detected when the non-speech data does not exist and then the packet data is inserted into a time slot of the non-speech data for transmission.
