使用二次特征选择及核融合的语音情感识别
Speech emotion recognition using secondary feature selection and kernel fusion
摘要
Abstract
To improve the recognition performance of speech emotion recognition, a high dimension acoustic feature set is constructed by basic acoustic features. A secondary feature selection method comprehensively considering the inherent properties between the features and emotions is adopted to select optimal subset with effective emotional recognizability. In the emotion recognition procedure, a binary tree structured multi-class classifier model is adopted to make compromise between total performance and complexity of the system. Kernel fusion method is utilized in SVM model to improve the recognition of the most confusable emotion. The experimental results of five emotions in Berlin database verify the effec-tiveness of the combination of secondary feature selection and kernel fusion on the improvement of emotional recognition accuracies and its robustness on noisy samples.关键词
