A dialogue system can present itself and/or address the user as an active agent by means of linguistic constructions in personal style, or suppress agentivity by using impersonal style. We describe how we generate and control per- sonal and impersonal style variation in the out- put of SAMMIE, a multimodal in-car dialogue system for an MP3 player. We carried out an experiment to compare subjective evaluation judgments and input style alignment behavior of users interacting with versions of the sys- tem generating output in personal vs. imper- sonal style. Although our results are consis- tent with earlier findings obtained with simu- lated systems, the effects are weaker.
