摘要
介绍了语音信号的3种端点检测方法,即能量过零率检测方法、基于频带方差的检测方法和语音短时信息熵检测方法,并对3种方法的优缺点进行分析。
In this paper, we introduced the three methods of endpoint detection of speech signal which are： detection methods of using zero-crossing rate, wave band variance, and voice comentropy. Also, we analyzed the advantages and disadvantages of these three methods.
