This method provides a filtering of blocks of digital samples of speech signal by a linear-prediction inverse filter followed by a shaping filter, whose coefficients are chosen out of a codebook of quantized filter coefficient vectors, obtaining a residual signal subdivided into vectors. Each vector...http://www.google.fr/patents/US4860355?utm_source=gb-gplus-shareBrevet US4860355 - Method of and device for speech signal coding and decoding by parameter extraction and vector quantization techniques
