Abstract :
In the present paper and its companion, the authors present the results of research on the real-time implementation of a speech coding system for use in an automobile environment subject to both road engine, and wind noises and acoustic echos. The authors emphasize a TMS320C30-based implementation of an finite-state VQ CELP coder operating at 5,000 bits per second
