摘要

现有的基于最小失真准则和迭代过程的语音矢量量化编码码本设计方法耗时长;而码本的质量测量，即平均失真，是无法预先确定的。本文提出了一种新的图书设计方法，这种方法一次性完成，节省了大量的计算机时间。对于任意给定的正ε值，我们都可以得到一个令人满意的码本，其平均失真度为\leq\varepsilon。

A new idea of code book design in vector quantization of speech

The now available method of code book design in vector quantization coding of speech, based on the minimum distortion criterion and an iterative process, is time-consuming; and the code book's quality measurement, the average distortion, can't be predetermined. This paper suggests a new method of book design which is a one-time process and saves a lot of computer time. And for any given positive value ε we can obtain a satisfactory code book, with its average distortionD\leq\varepsilon.
