Many further studies have been done on the basis of analyzing the autocorrelation algorithm in this paper.A band-pass filter and a tri-level clipping module was adopted to improve the detection which took the accuracy and the detection rate into account.Based on Matlab and processing a specific voice,the estimation method was designed,more accurate voice pitch period of the voice sound has been obtained.The experiments showed that the method was simple and efective.
