A speech dialogue management system for human interface employing visual anthropomorphous agent

A visual anthropomorphous agent with a realistic human face which moves in real-time on CRT responding to a user may become an important approach of advanced human interfaces in the near future. We are constructing such an interface system. This paper describes a speech dialogue function attached to the system. It enables one to develop a friendly guidance system through naturalistic conversation and facial expressions. Speech is an important medium for a human interface. The notable feature of our system is the integration of visual expression and speech dialogue; these two communication modalities can work together in human brain for better cognitive
