Abstract
An architecture including a speech manager that identifies input, input content, and location of the input (speech, for example), a action scheduler, a dialog manager, and an animation system provides reduced message traffic and streamlined processing for support of animated characters (conversational characters, for example). Speech recognition is provided along with location information to the action scheduler for determination of appropriate expressions for interactive behavior (looking, turn taking, etc.), and speech (or input) content is provided to a dialog manager to determine a substantive response (including speech or other content related responses) and any facial expressions or gestures related to content, but not containing content, are identified, and placed in a communication to the animation system.
