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 utternace, determining the "production values of "global speech rate" "for each emotion and attitude invovled inthe 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 wnet a step 'further with the analysis of "local"speech rate" realtive to neutrality, considering accented and non-accented speech "segments spearately. The perceptual relevance of variations in "lcoal speech "rate relative to neutrality" was then tested in a perception experimetn. Both global and local variations "appeared ot be relevant for conveying emotions and attitudes in speech.
