本文提出了一种利用二进制小波变换和短时自相关函数相结合的算法来检测语音信号的基音周期。它克服了单纯的短时自相关函数法对含噪语音检测时阈值难以确定的缺陷。-This paper proposes the use of a binary wavelet transform and short-time auto-correlation function of combining voice algorithm to detect letter Pitch No. cycle. It overcome

本文是小波分析在语音信号基音检测中的应用研究-This is the wavelet analysis of the speech signal pitch detection of study

运用matlab对语音信号进行基音检测，对检测出来的基音进行分析。
