Continuous Audio-visual Speech Recognition Continuous Audio-visual Speech Recognition
We address the problem of robust lip tracking, visual speech feature extraction, and sensor integration for audiovisual speech recognition applications. An appearance based model of the articulators, which represents linguistically important features, is learned from example images and is used to locate, track, and recover visual speech information. We tackle the problem of joint temporal model...
متن کاملMeasuring Audio and Visual Speech Synchrony: Methods
Speech is a means of communication that is intrinsically bimodal: the audio signal originates from the dynamics of the articulators. This paper reviews recent works in the field of audiovisual speech and more specifically on techniques developed to measure the level of correspondence between audio and visual speech. It overviews the most common audio and visual speech front-end processing, tran...
متن کاملAudio - Visual Speech Recognition
We have made signi cant progress in automatic speech recognition (ASR) for well-de ned applications like dictation and medium vocabulary transaction processing tasks in relatively controlled environments. However, for ASR to approach human levels of performance and for speech to become a truly pervasive user interface, we need novel, nontraditional approaches that have the potential of yielding...
متن کاملInfant perception of audio-visual speech synchrony.
Three experiments investigated perception of audio-visual (A-V) speech synchrony in 4- to 10-month-old infants. Experiments 1 and 2 used a convergent-operations approach by habituating infants to an audiovisually synchronous syllable (Experiment 1) and then testing for detection of increasing degrees of A-V asynchrony (366, 500, and 666 ms) or by habituating infants to a detectably asynchronous...
