| 摘 要： | 本文将子波变换应用于提取语音信号的谱包络参数。这种谱包络提取法模拟了人耳的频谱分辨特性，因而能很好地用于语音处理。与传统的ＬＰＣ谱包络提取法相比，它能降低所用的阶数。本文先介绍子波的基本原理，然后在此基础上介绍子波变换语音谱包络提取法及实验结果。

| Abstract: | This paper introduces the basic method applying the Wavelet Transform in the extraction of speech spectral envelope parameters. This method simulates the resolution features of human ears, so it is suitable for the speech processing. Compared with traditional LPC method, it can lower the order. At first we introduce the basic theory of Wavelet, then we introduce our work about the application of Wavelet Transform in the extraction of speech spectral envelope and give the experimental results. |
