    基于倒谱短时部分反映了语音的声道特性,先用汉明窗取一帧语音,然后经变换得到语音倒谱,将倒谱短时部分取出,进行正交反变换后将得到声道的对数谱,即得到语音频谱的包络。将频谱包络和频谱画在一张图上,有很好的对比效果。获取的包络效果十分好。(Based Cepstral partly reflects the short channel characteristics of the speech, first take a Hamming window with a frame of speech, and speech cepstrum obtained by converting the cepstrum short segment out inverse orthogonal transform to obtain channel will of the spectrum, i.e. to obtain the envelope of the speech spectrum. The spectral envelope and spectral painted on a chart, there is a good contrast. Get the envelope effect is very good.)

  • 提取信号基频
    用自相关函数提取语音信号基频,提取音频文件的基频等高线(Use the autocorrelation function on segments of the signal (windowsize: 100ms) and compute the fundamental frequency. Use a max_time_lag of 100ms in the autocorrelation function and a window shift of 25ms. Create a fundamental frequency vector and plot the pitch contour.)

    这是基于隐马尔可夫模型的连续语音识别代码,不同于dtw,这是个完整的工程,我把需要的voicebox也放进去了,一共用到9个子函数,包括模板的训练算法何识别算法,是完全可以使用的。(This is based on the hidden Markov model of continuous voice recognition code, different the dtw, which is a complete project, I need to put the voicebox into a total of nine sub-functions, including the template training algorithm to identify the algorithm, Is fully available.)
