9. A method for decoding data streams in a full-duplex voice communication system, comprising: receiving multiple sets of speech coding parameters, where each set of speech coding parameters was received over a different channel in the system; determining a weighting metric for each channel over which speech coding parameters were received; weighting the speech coding parameters using the weighting metric for the channel over which the parameters were received; summing weighted speech coding parameters to form a set of combined speech coding parameters; and outputting the set of combined speech coding parameters to a speech synthesizer.

The method of claim 9 further comprises receiving two or more data streams having voice data encoded therein at a receiver, where each data stream corresponds to a channel in the system, and decoding each data stream into a set of speech coding parameters.
