语音识别检测端点也就是采集声音信号的时候，开始说话到说话结束，我们把这一段声音信号采集下来进行处理。不然那么多信号都去处理，没有声音也处理那就浪费了很多的空间以及浪费了CPU去做后续的操作。这是一段语音识别检测端点代码。-Speech recognition detection endpoint is to collect the sound signal, began to speak to the end of the speech, we put this section of the s

语音预处理可视化程序设计。能够采集语音信号；实现语音预加重、过零检测、分帧等预处理；实现可视化界面设计，完成语音预处理过程显示。-Voice pretreatment

基于BP网络和多特征的语音端点检测，提取自相关函数最大值和频带方差作为BP网络输入，输出判断是否为语音信号。(A Speech Endpoint Detection Algorithm Based on BP Neural Network and Multiple Features)

对传输的语音信号进行端点检测，检测出端点后可进行加窗分帧而后进行短时傅里叶变换。(After the endpoint detection of the transmitted speech signal, after detecting the endpoint, windowed sub frame can be added, and then the short-time Fu Liye transform can be carried out.)

可对一段信号进行分帧加窗，利用过零率和短时能量检测语音端点(It can divide the frame into a window and use the zero crossing rate and short time energy to detect speech endpoints.)
