Abstract

Results are presented from a study on the vector quantization of spectral components. Three types of transform-based speech representation are examined, namely, a least-squares representation, a subband representation, and a pitch-harmonic representation. The spectral components associated with these representations are encoded using vector quantization techniques. The results of all the coding schemes are evaluated using signal-to-noise ratios and informal listening tests.
