Speech, and prosody in particular, is tightly linked to manual gestures . This study investigates the coordination of prosodic contrastive focus and different manual gestures (pointing, beat and control gestures). We used motion capture on ten speakers to explore this issue. The results show that prosodic focus "attracts" the manual gesture whichever its type. The temporal alignment between speech and the manual gesture is the strictest for pointing. It is realized between the pointing apex and an articulatory vocalic target whatever the position of focus within the utterance. Moreover, the results show that the production of a manual gesture, whichever its type, does not affect the acoustic and articulatory correlates of prosodic focus.
