Popis:	We address character (personality) expression for a spoken dialogue system in order to accommodate it in particular dialogue tasks and social roles. While conventional studies investigated controlling the linguistic expressions, we focus on spoken dialogue behaviors to express systems’ characters. Specifically, we investigate spoken dialogue behaviors such as utterance amount, backchannel frequency, filler frequency, and switching pause length in order to express three character traits: extroversion, emotional instability, and politeness. In this study, we evaluate this model with a natural spoken dialogue corpus. The results reveal that this model expresses reasonable characters according to the dialogue tasks and the participant roles. Furthermore, it is also shown that this model is able to express different characters among participants given the same role. A subjective experiment demonstrated that subjects could perceive the characters expressed by the model.
