    功率倒置算法的LMS实现,因为自己遇到了点问题,本人一直在找这个程序,没找到,故自己重新检查把问题发现了,相信如果你要实现的话可能会遇到这个问题祝你好运!(Power inversion algorithm LMS implementation, because they encountered a point problem, I ve been looking for this program, did not find it to re-examine the problem yourself discovered, I believe if you want to achieve, then you may encounter this problem Good luck!)

  • matlab计算基频率
    利用所给的中心削波,计算自相关/AMDF代码,选取一段语音,使用Praat预估其基音周期范围,合理设置预估的极值点距离等参数,计算并画出语音的基音频率曲线(By using the given center clipping, the autocorrelation /AMDF code is calculated, a speech is selected, the range of the pitch period is estimated by Praat, the estimated distance of the extreme point is set up reasonably, and the pitch frequency curve of the speech is calculated and drawn.)

    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 voice command (wake up word), so that the device enters the work state or completes an operation. In order to realize the function of speech wakeup, the device needs real-time monitoring, that is, real-time recording and analyzing whether or not wake words are used to wake up the equipment. There are three criteria for evaluating a voice wakeup system: wakeup accuracy, false positive rate, and power consumption. Generally, the higher the correct rate of arousal, the higher the false positive rate. A good system requires high wake-up rate, low false positive rate and low power consumption.)
