中文说明：资源描述 本程序是将短时能量和短时过零率相结合，采用双门限判定法来检测语音端点。先为短时能量和短时过零率分别确定两个门限，一个是较低的门限数值较小，对信号变化明显，容易超过，另一个是比较大的门限，数值较大。低门限被超过未必是语音的开始，有可能是噪声引起的，高门限被超过并且在规定的语音时间段内超过低门限，则意味着语音的开始
English Description：
Application background& nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; this procedure is the short-time energy and short-time over zero rate combination, using dual threshold decision method to detect the speech endpoint. First, the short-time energy and short-time zero crossing rate are respectively determined two thresholds, one is the lower threshold value is smaller, the signal change is obvious, easy to exceed, the other is a relatively large threshold, numerical. Low threshold is exceeded is not necessarily the beginning of speech, may be caused by noise, Highgate limit is exceeded and the provisions of the speech time period exceed the lower threshold, it means that the beginning of the speech
