Analysis by Synthesis of Embodied Communication via VirtualActor with a Nodding Response Model

In this study, we develop the embodied virtual communication system with the speech-driven nodding response model for the analysis by synthesis of embodied communication. Using the proposed system in embodied virtual communication, we perform experiments and carry out sensory evaluation and voice-motion analysis to demonstrate the effects of nodding responses on a talker's avatar called VirtualActor. The result of the study shows that superimposed nodding responses in a virtual .space promote communication.
