INTERSPEECH 2004 - ICSLP
This study examines some of the aritculatory differences in production of non-linguistic information, including spontaneous emotion vs. imitated emotion, para-linguistic information, in which the phrasing and intonational patterns were the same as in the first set of utterances with non-linguistic information, and linguistic information in which the same utterances were read. The findings suggest there are differences in articulation between imitated (acted) and spontaneous emotion. Specifically, for this particular emotional speech on the vowel /i/, tongue position was found to be higher and more forward, which suggests that emotional speech may be characterized by stronger lingual gestures.
