An investigation of emotion changes from speech

Abstract

Emotion recognition based on speech plays an important role in Human Computer Interaction (HCI), which has motivated extensive recent investigation into this area. However, current research on emotion recognition is focused on recognizing emotion on a per-file basis and mostly does not provide insight into emotion changes. In my research, emotion transition problem will be investigated, including localizing emotion change points, recognizing emotion transition patterns and predicting or recognizing emotion changes. As well as being potentially important in applications, the research delving into emotion changes paves the way towards a better understanding of emotions from engineering and potentially psychological perspectives.
