    语音合成程序源码!psalo频域基音同步叠加方法。它首先对原始语音信号进行短时频域变换,的到短时谱与短时谱包络。短时谱除以短时谱包络的到声源短时谱,对声源短时谱的实部与与虚部分别进行线性插值,就能达到改变变语音信号基频的目的,然后再进行频域反变换,可的到变换后的短时语音信号。短时谱包络部分也能独立改变,以达到改变音色的目的。 (Voice synthesis program source! psalo frequency domain pitch synchronous superposition method. It was first carried out on the original speech signal a short-time frequency-domain transform, to the short-time spectrum and short-time spectrum envelope. The short-time spectrum divided by the short-time spectrum envelope of the short time spectrum of the sound source, the short time spectrum of the real part of the sound source, and the imaginary parts of the linear interpolation, can achieve the purpose of changing the fundamental frequency of the alternating speech signal, and then then the inverse transform of the frequency domain, can be to the short-time speech signal after conversion. The short-time spectral envelope section can be varied independently, in order to achieve the purpose of changing the tone.)

    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.)
