In this research, we consider the use of non-verbal information in human-robot dialogue to draw the communication ability of robots close to that of human beings. This paper describes analysis of output timing of non-verbal information for the interactive dialogue between human beings. Moreover, we analyzed influences of output timing by controlling it in dialogue with a CG robot. As a result, we clarify the strength of constraint and naturalness of various types of non-verbal information. We also confirm that appropriate output timing of non-verbal information is the start of utterances. This is the same as in human-human dialogue. As a result, non-verbal information made speaker-change smooth for the CG robot.
