Abstract
The making of virtual human character to be realistic and credible in real time automated dialog animation system is necessary. This kind of animation carries importance elements for many applications such as games, virtual agents and movie animations. It is also considered important for applications which require interaction between human and computer. However, for this purpose, it is compulsory that the machine should have sufficient intelligence for recognizing and synthesizing human voices. As one of the most vital interaction method between human and machine, speech has recently received significant attention, especially in avatar research innovation. One of the challenges is to create precise lip movements of the avatar and synchronize it with a recorded audio. This paper specifically introduces the innovative concept of multimodal dialog systems of the virtual character and focuses the output part of such systems. More specifically, its focus is on behavior planning and developing the data control languages (DCL).
