摘　　要：文章对短时自相关测语音基音周期的方法进行改进,提出一种精确的基音周期测量方法。根据语音共振峰的特点,滤除高频分量,降低语音短时周期性对基音周期测量的影响。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.

关 键 词：基音周期 自相关 共振峰
