Abstract
The paper discusses how binary error-correcting codes can be used to provide (+1/-1)-waveform codebooks that speed up search in CELP vocoders. Four coding techniques operating at half bit per sample with respectively 8, 16, 24 and 32 samples are compared in terms of complexity and SNR performance, Recent results on spherical codes from regular point lattices are also reported.
