The Behavior Expression Animation Toolkit
|The Behavior Expression Animation Toolkit
(BEAT) allows animators to input typed text that they wish to be spoken by
an animated human figure, and to obtain as output appropriate and
synchronized nonverbal behaviors and synthesized speech in a form that can
be sent to a number of different animation systems. The nonverbal
behaviors are assigned on the basis of actual linguistic and contextual
analysis of the typed text, relying on rules derived from extensive
research into human conversational behavior. The toolkit is extensible, so
that new rules can be quickly added. It is designed to plug into larger
systems that may also assign personality profiles, motion characteristics,
scene constraints, or the animation styles of particular animators.
