本文根据倒谱系数矢量在特征空间的统计分布特性
提出了一种新的等方差加权倒谱失真测度
这种测度的加权函数充分刻画了语音倒谱矢量在特征空间分布的精细结构
从而有效地辨识不同讲话者的特征
实验表明
和常规的欧氏距离及方差倒数加权距离等相比
本文所提的失真测度能显著提高基于矢量量化的说话人识别的正识率。
Based on the statistical distributions of the cepstral coefficients in the fea-ture space
this paper proposed a novel equivariance weighted cepstral distortion measure. Since the new weighting function reflects the fine structure of the feature space composed of speech cepstral vectors
the individual feature of speakers can be identified much efficiently. Preliminary experiments show that
for the VQ based speaker recognition
the proposed weighted cepstral distortion measure works substantially better than the Enclidean distance or the inverse variance weighted cepstral distance.
