The linguistic behaviors analyzed in this study included the mean length of utterance, give-up and topic development frequency. Furthermore, we examined what kinds of pragmatic skills smart speakers need to sustain multiple turn-taking interactions. The results suggest that smart speakers' performance levels and pragmatic skills have different effects on linguistic behaviors. Task performance and the pragmatic levels of smart speaker did not change participants' utterance lengths. Giving up on conversations when tasks were not successfully completed occurred more frequently with smart speakers with low pragmatic capabilities. Topic development occurred more frequently when people interacted with smart speakers with high pragmatic capabilities or when tasks were accomplished. The notable requisite pragmatic skills for smart speakers included the abilities to specify and describe information, react to indirect behavior, and appreciate humor/ironic humor. The findings of this study may have implications for designing dialogue for artificial conversational agents in various conversational settings.
