What: Prosodic Structure in Speech Production and Speaker Interaction
Where: DZ 4
When: Thursday, 21 April 2016, 12:30 - 13:30 hours


Abstract

The term 'prosody' refers to linguistic structure above the segmental level, such as phrasal organization, rhythmic structure, and prominence. In addition to intonational events, prosodic structure introduces systematic variation in the temporal properties of speech. For example, acoustic and articulatory studies have shown that segments and speech movements (gestures) become longer in the vicinity of prosodic boundaries, and that this lengthening increases with boundary strength. Similarly, prominence leads to lengthening of segments and speech gestures. I will present a series of experimental studies examining how structural properties of prosody are reflected in speech production and how they are shaped by the broader context of language use. I start with an experimental study examining categoricity and gradiency in the production of prosodic boundaries. I then turn to prosodic convergence as manifested in rhythmic tuning between speakers. The last three studies examine the relationship between body gestures (specifically manual movements) and prosodic structure. The focus is on the coordination of manual and speech gestures (experiment 3) and on the temporal properties of manual gestures at prosodic boundaries (experiment 4) and under prominence (experiment 5). The implications of the findings for our understanding of the linguistic representation of prosodic structure are discussed.
