Detection of Auditory-Visual Asynchrony in Speech and Nonspeech Signals
Two experiments were conducted to examine the temporal limitations on the detection of asynchrony in auditory-visual (AV) signals. Each participant made asynchrony judgments about speech and nonspeech signals presented over an 800-ms range of AV onset asynchronies. Consistent with previous findings, all conditions revealed a wide window of several hundred milliseconds over which AV signals were...
متن کاملAudiovisual asynchrony detection for speech and nonspeech signals
This study investigated the “intersensory temporal synchrony window” [1] for audiovisual (AV) signals. A speeded asynchrony detection task was used to measure each participant’s temporal synchrony window for speech and nonspeech signals over an 800-ms range of AV asynchronies. Across three sets of stimuli, the video-leading threshold for asynchrony detection was larger than the audio-leading th...
متن کاملDetecting auditory-visual speech synchrony: how precise?
Previous research suggests that people are rather poor at perceiving auditory-visual (AV) speech asynchrony, especially when the visual signal occurs first. However, estimates of AV synchrony detection depend on many factors and previous measures may have underestimated its precision. Here we used a synchrony-driven search task to examine how accurately an observer could detect AV speech synchr...
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...
متن کاملChildren's perception of visual and auditory speech.
Preschool children's evaluation and integration of visual and auditory information in speech perception was compared with that of adults. Subjects identified speech events, which consisted of synthetic speech syllables ranging from /ba/ to /da/ combined with a videotaped /ba/, /da/, or no articulation. Both variables influenced the identification judgments for both groups of subjects. The resul...
