基于Matlab的一种基音周期检测算法

在对自相关基音检测算法进行分析的基础上,对此算法进行了深入探讨,针对以往研究中存在的不足加以改进,考虑到检测准确度和检测速率两方面的因素,引入了三电平削波模块,设计了基于Matlab的估计方法,然后通过对一段具体的语音进行处理,得到了比较准确的浊音语音的基音周期.实验证明,该方法简单、有效.

An algorithm for pitch detection based on Matlab

In this paper,some further studies have been done on the basis of analyzing the autocorrelation algorithm.For the shortcomings of the research in the past,a tri-level clipping module is adopted to improve the detection which takes the accuracy and the detection rate into account.This paper designed the estimation method based on Matlab,and then through processing a specific voice,obtained more accurate voice pitch period of the voiced sound.The experiments show that the method is simple and effective.
