Abstract
A voice encoder and decoder which attempt to minimize the effects of voice data packet loss, typically over wide area networks is provided. The voice encoder utilizes future data, such as the lookahead data typically available for linear predictive coding (LPC), to partially encode a future packet and to send the partial encoding as part of the current packet. The decoder utilizes the partial encoding of the previous packet to decode the current packet if the latter did not arrive properly.
