关于语音识别中的端点检测的代码和资料 用matlab实现的 依据 短时能量 过零率 -Speech Recognition on endpoint detection matlab code and data with the basis to achieve zero rate of short-term energy

语音信号预处理matlab程序，在7.0上运行通过，可以做实验参者代码（包括：lpc 谱、短时谱分析、短时过零率、短时能量、语音端点检测等）-Matlab voice signal pre-processing program, run through the 7.0, you can experiment with participation by the code.

语音信号时频分析，包括语谱图，过零率，自编的自相关，以及最后用了三种方法（短时能量和过零率、谱熵法、Teager算子）进行端点检测，代码完整且测试通过-time and frequency domain analysis of speech signals,including spectrogram,rate of zerocrossing,autocorrelation.and three method of endpoint detection,especially the Teager
