说明：  通过matlab设计的GUI界面实现语音信号的实时录入和频谱分析和滤波等处理，并能够显示各阶段时域波形及频谱图，滤波器种类及参数可调(Through the GUI interface designed by matlab, the real-time input of speech signal, spectrum analysis and filtering are realized, and the time-domain waveforms and spectrograms of each stage can be displayed, and the types and parameters of filters can be adjusted.)

说明：  假如数据中有N 个变量，而我们想抽取的样本的数量是M,那么在对数据进行抽样的时候，这种方法首先会把N个变量的设计空间均匀的划分开为M份，然后在每个划分好的区域中随机的抽取一点，最后，从这M个变量里，随机挑选之前选好的点，构成我们的样本(If there are n variables in the data, and the number of samples we want to extract is m, then when sampling the data, this method will first divide the design space of n variables into M parts evenly, and then randomly extract a point in each divided area. Finally, from the m variables, randomly select the previously selected points to form our sample)
