这是一个简单的语音基音检测方法，通过对语音信号进行滤波、分帧、求自相关函数，可得到浊音的基音周期，从而实现基频检测。-This is a simple voice pitch detection, voice signals by filtering, sub-frame, find the autocorrelation function, voiced the pitch period available to achieve the fundamental frequency testin

语音基音频率的检测方法matlab编程 自相关法和同态滤波法-Pitch detection methods matlab programming frequency autocorrelation and homomorphic filtering

This MATLAB exercise designs and implements a pitch period detector based on detecting and tracking peaks in the autocorrelation of the LPC error signal during regions of voiced speech. The pitch detection procedure is called the SIFT (Simple Inverse
