Abstract
A method for transmitting speech of a first person communicating with a second person via a packet switched network comprising: generating a stream of samples of the first person's speech during the communication; parsing the sample stream into audio frames; determining which audio frames correspond to periods when the first person is speaking and which correspond to periods when the first person is silent; transmitting audio frames corresponding to silent periods and speaking periods of the first person's speech; and transmitting at least some of the audio frames corresponding to speaking periods, but none of the audio frames corresponding to silent periods, at least twice.
