<p>LPC code vectors are preliminarily selected out of many LOPC code vectors stored in an LSF code book (101) with a weighting Euclid distance as a measure, and LPC code vectors left after the preliminary selection are subjected to code-final-selection with distortion amount in spectrum space as a measure, whereby enhancing the quantizing performance of a vector quantizing device for LPC parameters to thereby improve the quality of synthesized voice in a voice coding/decoding device.</p> |
