【摘要】:用多窗譜估計(jì)和伽馬通濾波改進(jìn)經(jīng)典的梅爾倒譜特征(MFCC)的識(shí)別性能,并與delta特征相結(jié)合,提出了一種基于加權(quán)參數(shù)設(shè)置策略的混合特征話者識(shí)別算法.該算法解決了梅爾倒譜系數(shù)方差過(guò)大、聽(tīng)覺(jué)特征不明顯及話者識(shí)別算法特征單一的問(wèn)題.仿真結(jié)果表明:與MFCC和線性預(yù)測(cè)的提取方法相比,該算法魯棒性能更優(yōu),對(duì)不同噪聲環(huán)境的適應(yīng)性更好.
[Abstract]:In this paper , the recognition performance of classical Mel cepstrum feature ( MFCC ) is improved by multi - window spectral estimation and gamma filtering and combined with delta feature . The algorithm solves the problem that the variance of the Mel cepstrum coefficient is too large , the auditory characteristic is not obvious and the speech recognition algorithm is single . The simulation results show that the robustness of the algorithm is better than that of MFCC and linear prediction , and the adaptability of the algorithm is better for different noise environments .
