说明： 端点检测是指用数字处理技术来找出语音信号中的各种段落（如音素、音节、词素、词等）的始点和终点的位置。语音段起止端点检测是语音分析、语音合成和语音识别中的一个必要环节。传统的端点检测方法是从wav文件中获取语音采样，将其分帧并计算短时能量和过零率参数，然后进行端点检测。这种工作方式被称为离线处理方法 ，无法实现语音信号的实时处理，对于语音信号分析具有一定的局限性。本文通过开发ActiveX控件，在MATLAB环境下将其嵌入到figure窗口中，以GUI程序的方式使用，实现语音信号端点检测的实时处理。(Endpoint detection is the use of digital processing techniques to identify the speech signals in a variety of paragraphs (such as phoneme, syllable, morpheme, word, etc.) the starting point and the end position. Speech endpoint detection is a paragraph beginning and end speech analysis, speech synthesis and speech recognition of a necessary link. Traditional endpoint detection method is to obtain from the wav file voice sampling, its sub-frame and calculate the short-term energy and zero-crossing rate parameters, and then proceed to endpoint detection. This work is called off-line approach can not achieve real-time speech signal processing, analysis of the speech signal has a certain limitations. In this paper, through the development of ActiveX controls, in the MATLAB environment to embedded figure window to use GUI program, the realization of speech signal processing real-time endpoint detection.)

说明： 自己用VC编写的一个读取wave文件，并计算短时能量、短时过零率以及自相关函数的程序。所有的计算结果都会显示在程序运行后生成的文本文档中。注意，运行程序时需要修改wave文件路径，在程序中体现为wavefilename字符串指针所指向的内容。(own VC prepared a document reader wave and short-term energy calculation, Short-term rates and zero autocorrelation function procedures. All the results will show in the running after generation of text documents. Attention, operating procedures need to amend the wave paper trails. the procedure embodied wavefilename string of indicators pointing to the contents.)
