Summary:We examine "hedges" - speech and nonverbal communication strategies that can reduce the categorical nature of the messages, connected with social face loss by the speaker or a face threatening act to the hearer. In the REC multimodal corpus, these speech acts and corresponding nonverbal actions (automanipulations, lip biting, etc.) are used (a) as politeness strategies, and (b) as an expression of the speaker's uncertainty. We reproduced these gestures on a companion robot in a situation, where the robot is answering exam questions by the user and makes minor mistakes. We have compared the perception of (a) a robot, using hedges, and (b) a robot, addressing the hearer after an utterance. The robot, using hedges, is perceived as more friendly and sympathetic, while nervous and hesitating, and the robot using the addressive expression is perceived as clearer, but detached.
