| Abstract: | This paper describes a high-quality middle-rate speech vector quantizer. In order to enhance synthetic speech quality,we use Itakura-Saito distortion mea- sure in LPC analysis,and multi-dimension residue vector as excitation.Through computer simulation,it can be proved that some methods that we use in training code-book are effective. |
