The purpose of this research is to propose a dialogue design for communication robots through non-task-oriented dialogue. The robot's expression of internal states, such as emotions and thoughts, is used for smooth communication and the establishment of close relationships. However, in previous studies in which internal states were expressed by utterances, it has been pointed out that users sometimes do not feel internal states from robots as stated. To solve this problem, we propose the dialogue robot that uses utterances not addressed to another individual (so-called “soliloquies”). The experimental results suggest that soliloquy is a more effective way to increase the degree of anthropomorphism in the robot than talking to users when the robot expresses subjective opinions. Based on these results, we developed an autonomous dialogue android that expresses its internal states including soliloquy and discussed the effectiveness of the system.
