Abstract
This paper proposes a novel utterance generation mechanism for a Talking-Ally robot through the utilization of the concepts of hearership and addressivity. The approach incorporates an addressee’s eye-gaze behaviors (state of hearership) in order to produce the utterances (addressivity) necessary for achieving smooth communication (synchronized with bodily interactions), which are perceived as being persuasive by the addressee. The results of the study show that the resources of the hearer were significant in generating or adjusting to the structure of utterances in order to persuade the addressee. Additionally, an analysis of dynamic interactions revealed that both the human and robot influenced each other’s behaviors—e.g., the robot influenced the addressee’s attention and the human influenced the robot in changing its utterances. The results of a subjective rating indicated that the robot recognized the participants as hearers, and it was also capable of utterance generation and behaved autonomously (robotic life-likeness), which proved to be crucial in enhancing the persuasiveness of the robot’s communication.
