基于短时能量和短时过零率来实现语音端点检测。也称为双门限比较法，是一种传统的 语音端点检测方法。现在已经有研究人员提出若干其他更加高效和有效的检测方法，但 是这个方法不失为一种最简单的方法，可以通过程序来获得语音端点检测的感性认识和 体会。内的程序读取WAV文件，程序附有详细的使用说明和注释，以及若干测试用的语音文件。(Based on the short-term and short-term energy to achieve zero rate of voice activity detection. Also known as dual-threshold comparison method, is a traditional method of voice activity detection. Researchers now have made a number of other more efficient and effective detection methods, but this method may be one of the most simple way to get through the process of voice activity detection and the experience of perceptual knowledge. Procedures within the WAV file to read, procedures with detailed instructions and notes, as well as the voice of a number of test documents.)
