摘要：
A method for improving packetized speech transmitted over a wireless LAN is disclosed. Speech packets transmitted over the wireless LAN are monitored for errors. Any of the speech packets found to have errors are replaced with synthesized speech packets. The synthesized speech packets may be created from a vocal tract model generated from the received speech packets during periods of time when there are no errors.
