Abstract

Automatic Speech Recognition (ASR) is the most natural input modality from humans to machines. When the hands are busy or a full keyboard is not available, speech input is especially in demand. Since the most compelling application scenarios for ASR include noisy environments (mobile phones, public kiosks, cars), visual speech processing must be incorporated to provide robust performance. This chapter motivates and describes the MPEG-4 Face and Body Animation (FBA) standard for representing visual speech data as part of a whole virtual human specification. The super low bit-rate FBA codec included with the standard enables thin clients to access processing and communication services over any network including enhanced visual communication, animated entertainment, man-machine dialog, and audio/visual speech recognition.
