%X In this paper, some methods are proposed to discriminate utterances from the speech signal. A corpus containing emotional speech of happiness, anger, surprise and sorrow with over 300 utterances from five speakers is recorded. Ten emotional features are extracted from the speech signal. Three emotion recognition methods are introduced based on principal component analysis. Using these methods, recognition performance is obtained, which is close to human performance on the task.
