The timing to generate communicative actions and utterance in face-to-face greeting interaction is analyzed by synthesis for applying to a human-agent interaction support based on the previous results in human-robot interaction. First, the synthesis system is developed by using a CG character which has the same appearance as the embodied robot in the previous study. Then, the analysis by synthesis is performed by using the CG character and confirms that the variation of the pause and lags of utterance to communicative actions brings different communicative effects, i.e. about 0.3 sec lag is desirable for familiar greetings, and the longer lag is for polite greetings. The result in CG character is the same as that in robot. These results demonstrate the importance of timing control in agent-to-human embodied interaction and the universal applicability in advanced human-agent communication.
