算法是在MATLAB环境下编译的，其实现的功能主要是采用小波包BARK域中子带方差法来实现端点检测，实验结果表明在高信噪比情况下效果显著-Algorithm is compiled in MATLAB environment, and its main function is implemented using wavelet packet BARK sub-band variance jurisdictions to implement endpoint detection, experimental results show that at high SNR significant effect
