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.
