Speech and Vision Lab

Speech carries information not only about the lexical content, but also about the age, gender, signature and emotional state of the speaker. Speech in differ- ent emotional states is accompanied by distinct changes in the production mechanism. In this chapter, we present a review of analysis methods used for emotional speech. In particular, we focus on the issues in data collection, feature representations and devel- opment of automatic emotion recognition systems. The significance of the excitation source component of speech production in emotional states is examined in detail. The derived excitation source features are shown to carry the emotion correlates.
