endpoint_detection
- 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.)
过零率计算源代码
- 语音端点的检测，不能只以能量的大小进行检测。人声和周边噪音，都可能拥有足够的能量，因此单独能量无法准确检测端点。而过零率在这一点上，则可以起到很大的效果。因此，端点检测时，过零率是不可以缺少的。(Adding zero crossing rate, can accurate detect. Human speech has more zero crossing rate.)

ABSE
- 熵值越大则每个符号包含的平均信息量越大。有研究发现，在有噪声的语音信号中，语音信号的熵和噪声信号的熵存在着较大的差异，对噪声信号来说在整个频带内分布相对平坦，熵值小，语音信号集中在某些特定频段内，熵值大。因此利用这个差异可以区分噪音段和语音段。(The greater the entropy is, the greater the average information of each symbol is. It is found that, in noisy speech signals, t
