| Abstract: | In this paper, a new method is proposed to measure the accurate pitch period, which is based on short-term autocorrelation algorithm. Ac- cording to the characteristics of the formants, we filter out high frequency components, to reduce the impacts of short-term cyclical signals in the voice, which can improve the accuracy of pitch period measurement. |
