本文提出了一种利用语音信号分布特性的矢量量化方法。此方法的主要特点是利用语音信号的概率分布在不同子空间中的相似性,减小设计码书的尺寸及搜索空间。
This paper presents a vector quantization method that uses the distribution of speech signals. The main feature of this method is the use of the probability distribution of speech signals in different subspaces to reduce the size of the design code book and search space.
