摘要

In natural communication, humans enrich their utterances with pragmatic information indicating, e.g., what is important to them or what they are not certain about. We investigate whether and how virtual humans (VH) can employ this kind of metarcommunication. In an empirical study we have identified three modifying functions that humans produce and perceive in multimodal utterance, one being to create or attenuate focus. In this paper we test whether such modifying functions are also observed in speech and/or gesture of a VH, and whether this changes the perception of a VH overall. Results suggest that, although the VH's behaviour is judged rather neutral overall, focusing is distinctively recognised, leads to better recall, and affects perceived competence. These effects are strongest if focus is created jointly by speech and gesture.
