Abstract
Trellis-coded quantization is incorporated into a predictive coding structure for encoding sampled speech. Systems are developed using fixed-prediction/fixed-residual encoding, fixed-prediction/adaptive-residual encoding, and adaptive-prediction/adaptive-residual encoding. For a fully adaptive 16-kb/s speech coding system, segmental signal-to-noise ratios in the range of 17. 5 to 20. 2 dB are obtained for a variety of speakers and test sentences. Reconstructed speech obtained from this system can be described as being of excellent communications quality.
