Abstract [en]

This paper reports on the analysis of the spectral variation of emotional speech. Spectral envelopes oftime aligned speech frames are compared between emotionally neutral and active utterances. Statisticsare computed over the resulting differential spectral envelopes for each phoneme. Finally, thesestatistics are classified using agglomerative hierarchical clustering and a measure of dissimilaritybetween statistical distributions and the resulting clusters are analysed. The results show that thereare systematic changes in spectral envelopes when going from neutral to sad or happy speech, andthose changes depend on the valence of the emotional content (negative, positive) as well as on thephonetic properties of the sounds such as voicing and place of articulation.
