A silence-suppression scheme for a packet voice transmission system (FIG. 1) accurately regenerates the silence signals at the receiving end. The following discipline is implemented at the transmitting end (100): if speech is detected (200), transmit (204) a packet carrying the speech; if silence is detected (200) and the last-transmitted packet carried speech (202), transmit (204) a packet carrying the silence; if silence is detected (200) and the last-transmitted packet carried silence (202), transmit nothing. The following discipline is implemented at the receiving end (101): if a packet is received during a packet time interval (300), output (302) the contents of the packet; if a packet is not received during a packet time interval (300), output (306) again the contents of the last-received packet. Thus, while only one silence-carrying packet is transmitted, the receiver regenerates silence signals for the entire silence interval. Also, no special transmission protocol is required to implement this scheme.
