| Abstract: | Autocorrelation pitch period detection is a key technique in voice signal process.Efficiency of the algorithm is also important except for the quality of the signal process.Pitch period of the dull sound is obtained through the short-time autocorrelation function,and polarity correlation and peak value estimation are used to raise the efficiency in the process of the autocorrelation. |

| Keywords: | autocorrelation pitch period polarity correlation |
