In multimodal human-robot interaction(HRI), the process of communication can be established through verbal, non-verbal, and/or para-verbal cues. The linguistic literature [3] shows that para-verbal and non-verbal communications are naturally synchronized. This research focuses on the relation between non-verbal and para-verbal communication by mapping prosody cues to the corresponding arm gestures. Our approach for synthesizing arm gestures uses the coupled hidden Markov models (CHMMs), which could be seen as a collection of HMMs modeling the segmented prosodic characteristics' stream and the segmented rotation characteristics' streams of the two arms' articulations [4][1]. Nao robot was used for tests.
