The present study investigates temporal characteristics of speech conveying emotion and attitude. First, a production study was conducted at the global level of the whole utterance, determining the production values of "global speech rate" for each emotion and attitude involved in the study. A perception study was also carried out at this global level, seeking perceptually optimal "global speech rate" values for conveying each emotion and attitude. Perception and production values were compared. Second, as more local information inside utterances might be specific to particular emotions or attitudes, the study went a step further with the analysis of "local speech rate" relative to neutrality, considering accented and nonaccented speech ½segments separately. The perceptual relevance of variations in "local speech rate relative to neutrality" was then tested in a perception experiment. Both global and local variations appeared to be relevant for conveying emotions and attitudes in speech.
