Research Abstract

This study proposed a method of emotion recognition in speech, which can estimate not only the emotion itself but the degree of each emotion from speech that plural emotions are included in. This method represents each emotion as a resultant vector of the basic factor vectors, Arousal-Valence-Dominance. As the results of applying this method with our already proposed emotion perception model to emotion recognition in speech, the mapping of speech to the emotional space is the most correspondent to human responses. In addition, the recognition accuracy is also greatly excellent at the recognition rate compared with that by GMM.
