- 语音唤醒就是在设备待机状态下，用户说出特定的语音指令（唤醒词）使设备进入工作状态或完成某一操作。设备为了实现语音唤醒功能，就需要设备实时监听，也就是实时的录音并分析有没有唤醒词来唤醒设备。评价一个语音唤醒系统的标准有三个：唤醒正确率、误报率、功耗。一般情况下，唤醒正确率越高 ，误报率也越高。好的系统就需要唤醒率高，误报率低，功耗低。(Speech wakeup is when the device is in standby mode, the user speaks a particular
ICA
- 本程序音频共有四个，借助鸡尾酒会问题思想，用ica算法实现四个音频的分离(The audio program for a total of four, with the help of the cocktail party problem, realizing the separation of four audio using ICA algorithm)

- 语谱图的横坐标是时间，纵坐标是频率，坐标点值为语音数据能量。由于是采用二维平面表达三维信息，所以能量值的大小是通过颜色来表示的，颜色深，表示该点的语音能量越强。(The spectral abscissa graph is time, the vertical axis is the frequency of speech data for energy point coordinates. Since the two-dimensional information is expressed i
