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 kbps 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
