摘　　要：首先简介语音信号端点检测涉及到的几个基本概念,然后采用短时平均幅度与短时平均过零率相结合的双门限算法来对语音信号进行端点检测。重点阐述双门限算法的设计思想与实现过程,经Matlab编程实验证明,该方法准确、有效。This paper firstly introduces some related concepts of speech end-point detection, and then makes end-point detection by the combination of short time average magnitude and short time average zero-crossing rate. Focusing on dual-threshold algorithm design and implementation of the process, the Matlab programming experiment proved that the method is accurate and effective.
