Infant 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...
متن کاملTesting Audio-Visual Familiarity Effects on Speech Perception in Noise
The current study investigated the effect of familiarity with the voice and face of a talker on a subsequent speech intelligibility task. Participants were first familiarized with four animated characters that they learned to identify by voice, by face and by both face and voice. Ceiling level performance was reached. Following this training, participants were given a speech in noise identifica...
متن کاملStimulus intensity and the perception of duration.
This article explores the widely reported finding that the subjective duration of a stimulus is positively related to its magnitude. In Experiments 1 and 2 we show that, for both auditory and visual stimuli, the effect of stimulus magnitude on the perception of duration depends upon the background: Against a high intensity background, weak stimuli are judged to last longer. In Experiment 3 we s...
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 Vision: Using Audio-Visual Synchrony to Locate Sounds
Psychophysical and physiological evidence shows that sound localization of acoustic signals is strongly influenced by their synchrony with visual signals. This effect, known as ventriloquism, is at work when sound coming from the side of a TV set feels as if it were coming from the mouth of the actors. The ventriloquism effect suggests that there is important information about sound location en...
