    基于谱减法的语音降噪处理,里面有声音文件,可以直接运行观察效果(Based on the spectral subtraction speech denoising processing, there are sound files, can be run directly observed effect)

    计算语音的短时平均能量。可以作为清音和浊音的特征参数,可以作为有声无声的依据(Calculate the short-term average energy of speech. It can be used as a characteristic parameter of voiceless and unvoiced sounds, and as a basis for sound and silence.)

    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.)

  • LPCC
    线性预测倒谱系数(Linear Prediction Cepstrum Coefficient,LPCC)是线性预测系数(Linear Prediction Coefficient,LPC)在倒谱域中的表示。该特征是基于语音信号为自回归信号的值设,利用线性预测分析获得倒谱系数。(Linear Prediction Cepstrum Coefficient)
