摘要： 提出一种基于语音短时自相关函数的基音提取实用方法。根据汉语语音短时能量和过零率相结合来精确定位汉语音节的的母基音周期起点，进而提取基音周期。经过大量的测试，结果与手工提取的精度一致。

Abstract: In this paper, a practical algolithm is presented. We can get thc precise beginning point of voiced part of Chinese syl1able intelms of shorttime average energy and average zero-crossing rate of Chinese syllable and exttaet the pitch period using traditional shorttimeauto-correlation function .T-he result is credible through a test on a large sum of vocabulary.
