代码说明：

说明：  傅里叶变换是一种分析信号的方法，它可分析信号的成分，也可用这些成分合成信号。在分析信号时，主要应用于处理平稳信号，通过傅里叶变换可以获取一段信号总体上包含哪些频率的成分，但是对各成分出现的时刻无法得知。(The Fourier transform is a method of analyzing a signal. It can analyze the components of a signal or synthesize a signal from those components. In the analysis of signals, it is mainly applied to the processing of stationary signals. Through the Fourier transform, it is possible to obtain the components of which frequencies a segment of signals contains in general, but it is impossible to know the time when each component appears.)

    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.)
