Description: 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 overcomes the simple short autocorrelation function of the noisy voice detection threshold when it is difficult to determine deficiencies.
