Expression of emotion and attitude through temporal speech variations

TL;DRAbstract

The present study investigates temporal characteristics of speech conveying emotion and attitude. First, a production study was conducted at the level of the whole utterance, determining the production values of global speech for each emotion and attitude involved in the study. A perception study was also carried out at this level, seeking perceptually optimal global speech values for conveying each emotion and attitude. Perception and production values were compared. Second, as more information inside utterances might be specific to particular emotions or attitudes, the study went a step further with the analysis of local speech relative to neutrality, considering accented and nonaccented speech segments separately. The perceptual relevance of variations in local speech rate relative to neutrality was then tested in a perception experiment. Both and variations appeared to be relevant for conveying emotions and attitudes in speech.
