An avatar in cyberspace can bring us a virtual face-to-face communication environment. In this paper, we realize an avatar which has a real face in cyberspace and construct a multi-user communication system by voice transmission through network. Voice from microphone is analyzed and transmitted, then mouth shape and facial expression of avatar are synchronously estimated and synthesized on real time.
