说明：  这里是一些代码，与matlab有关，是一些小技巧。(code, and the Matlab is some small skills.)

通过改变想要处理的帧，和预测器阶数，对原始语音帧和预测语音帧作一个比较，并作出短时谱和lpc谱，最后作倒谱比较。(By changing the processing of the desired frame, and the predictor order, the original speech frame and the predicted speech frame to make a comparison and to make short-term spectrum and the lpc spectrum, cepstrum last for comparison.)

说明：  能够对于奇异值的计算matlab代码，它可以加强攻击性的抵抗能力。(Singular value can be calculated for the matlab code, which can enhance resistance to attack.)
