Abstract

A method and apparatus for reducing voice latency in a voice-over-data wireless communication system. In a transmitter, audio information to be transmitted is first encoded using a voice encoder operating in a first mode of operation. At least one operating parameter in the transmitter is measured by a processor, the least one operating parameter proportional to a latency between the transmitter and receiver. If the at least one operational parameter exceeds a predetermined threshold, the voice encoder is instructed to operate in a second mode of operation. When the at least one operational parameter falls below a second predetermined threshold, the voice encoder is instructed to operate in the first mode of operation.
