Emotional speech is produced when a speaker is in a state different from normal state. The objective of this study is to explore the deviations in the excitation source features of an emotional speech compared to normal speech. The features used for analysis are extracted at subsegmental level (1.3 ms) of speech. A comparative study of these features across different emotions indicates that there are significant deviations in the subsegmental level features of speech in emotional state when compared to normal state.
