摘 要: 本文针对语音信号的矢量量化码书进行了研究。利用矢量量化码书的码字和值及码字差值作为码书的特征变量,对不同语音信号的矢量量化码书分布情况做了分析,并给出了若干结果。 Vector Quantization (VQ) codebooks of speech signals are researched in this paper.Codeword expection or codeword difference is chosen as characteristic variable and correlative coefficients of charcteristic variable sequences are presented ,which are used to analyze the VQ codebooks of different speech signals. Some results are shown.
