Speech-Driven Avatar Robot System with Changing Complexion for the Visualization of an Interactive Atmosphere

摘要

Smooth interactions between talkers can be realized by transmitting and receiving mutual video images and voices in remote communication. However, in such remote communication, it is difficult to generate a sense of unity and an interactive atmosphere because humans recognize screens as a boundary of the physical space. Therefore, it is essential to develop a communication system that can generate and share an interactive atmosphere and interaction-activated communication even if talkers are in remote places. In this study, we developed a speech-driven avatar robot system incorporating an estimation model that simulates the degree of activated communication based on the talker’s speech. The developed avatar robot system can visualize an interactive atmosphere while changing the complexion based on an estimated value. The effectiveness of the developed system was demonstrated by means of sensory evaluations.
