A large network delay would obstruct human interaction using telecommunication systems such as telephony or video conference. Studies on the embodied communication support in the network delay condition have been little undertaken despite considerable investigations of the network delay of voice and image data. It is important that the ways of revealing the delay are discussed for smooth human interaction. We have already developed an embodied virtual communication system using an avatar called "VirtualActor" in which remote talkers can share embodied interaction in the same virtual space. It has been confirmed that the fixed 500ms network delay has no effects on interaction via VirutalActors in the questionnaire in the communication experiment. In this paper, we propose the presentation method of talker's voice and avatar's motion feedback in the 1.5s network delay condition by using VirtualActors. The communication experiment is performed under the conditions of a free conversation by 5 scenes; the real-time scene without the network delay, and the 4 remained network-delay scenes for the combination of the delay of the talker's voice and his/her avatar's motion feedback. The subjects consisted of a total of 15 pairs of 30 students who are familiar with each other. Sensory evaluation shows communication effects of the delay of avatar's motion feedback on interaction support.
