The use of channel coding in low bit rate speech coders face a performance upper bound with the limited redundancy permitted. Thus, the speech quality can degrade in bad channel transmission conditions. This paper describes a error control configuration which exploits source redundancy to enhance the performance of the channel decoder, possibly beyond maximum likelihood performance
