Mallat算法用于语音信号分析与压缩

Application of Mallat's Algorithm to the Analysis and Compression of Speech Signal

    摘要
  • 摘要: 给出了一种基于小波变换的汉语语音信号预处理的方法。通过小波变换中的Mallat算法来分解汉语语音信号,能够消除信号冗余度,提高数据压缩比,而不影响语音信号的真实效果。同时还给出了小波变换原理和Mallat算法以及实验结果。

     

    Abstract: The Mallat's Algorithm in wavelet transforms is used to preprocess the chinese speech signal. By decomposing the speech signal, the compression ratios is improved under the certain distortion degree. The theory of wavelet transforms and the Mallat's Algorithm are proposed and the method is verified by the experimental results.
