基于小波改良动态Mel倒谱声纹识别算法研究

摘要

在传统Mel倒谱系数提取过程的基础上，结合离散小波变换，提出了改良动态Mel倒谱系数及基于小波改良的Mel倒谱系数，给出了相应的算法。不同语音长度和信噪比实验表明，该算法使得系统识别率和鲁棒性得到了提高。%In this paper,an improved dynamic Mel-frequency cepstrum and an improved dynamic Mel-frequency ceps-trum based on wavelet transform is proposed. The corresponding algorithm is given too. Different speech length and SNR experiments show that the system recognition rate and robustness are all improved.
