چکیده
We describe the CASSI (Computer Animated Speech SImulator) software system, which creates facial animations corresponding to X-ray microbeam data. Each data le records a sequence of positions of the tongue, lips, and jaw of a human subject. The CASSI system utilizes Parke's model of a human head, augmented by a representation of the inside of the mouth, including the tongue. CASSI's output is a 3D facial animation that shows, in animated form, a subject's facial movements while speaking and performing other tasks. The output animations are subjectively evaluated with respect to the positions of the teeth, lip, and tongue for a variety of human subjects and tasks.

The Impact of Auditory Embodiment on Animated Character Design
Advances in speech recognition and text-to-speech (TTS) technologies recently have contributed to the development of conversational interfaces that incorporate animated characters. These interfaces potentially are well suited for educational software, since they can engage children as active learners and support question asking skills. In the present research, a simulation study was conducted i...

The Olga project has developed an animated agent interface for information services. The interface combines a graphical interface, spoken dialogue and an animated 3D ‘human-like’ character for multimodal interaction with users. The interaction is intelligently managed using techniques derived from spoken dialogue but extended for the graphical modality. The Olga agent is innovative in combining...

This paper presents the virtual speech cuer built in the context of the ARTUS project aiming at watermarking hand and face gestures of a virtual animated agent in a broadcasted audiovisual sequence. For deaf televiewers that master cued speech, the animated agent can be then incrusted on demand and at the reception in the original broadcast as an alternative to subtitling. The paper presents th...
