ABSTRACT:
A voice encoder which 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. A decoder utilizes the partial encoding of the previous packet to decode the current packet if the latter did not arrive properly.
