一种基于关系度量融合框架的说话人认证特征级融合算法
Feature Level Fusion Based on Speaker Verification via Relation Measurement Fusion Framework
摘要
Abstract
This paper investigates the possibility of the feature level fusion based on speaker verification. According to the robustness and availability of the relation measurement fusion framework, the feature level fusion based on speaker verification is established. Through comparison of performances among the feature level fusion, traditional matching-score level fusion, and unimodal algorithms, the experimental results show that the proposed method is the best. To further analyze its correctness, this paper introduces the maximum Kullback-Leibler distance of the aspect of information theory to measure the information content. This distance overcomes the shortcoming of the asymmetry by traditional Kullback-Leibler distance and improves the precision of the information content computation. And the computational results verify the effectiveness of our algorithm, indicating that the feature level fusion can hold more discriminative information than the existing matching-score level fusion to yield a better performance.关键词
