摘要 论文基于矢量量化模型下的说话人识别系统,研究了几种说话人特征,即线性预测系数(LPC)及其导出的特征,包括线性预测倒谱系数(LPCC),反射系数(REFL),对数面积比系数(LAR),反正弦系数(ARCSIN)和线谱频率(LSF),以及共振峰。仿真实验中,对比了不同参数设置情况下这些特征的分类误差,总结出线性预测分析在应用于说话人特征提取时选择参数的规律。 With the speaker recognition system based the model of VQ,this paper surveyes the LPC and LPC-Derived feature sets including,LPCC,REFL,LAR,ARCSIN,LSF,and formants as well.In the experiment,comparing the performance of various feature sets under different parameter backgrounds,the method selecting parameters for LPA in speaker features has been obtained.
