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...

Audiovisual 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...

Representing nonspeech audio signals through speech classification models

The human auditory system is very well matched to both human speech and environmental sounds. Therefore, the question arises whether human speech material may provide useful information for training systems for analyzing nonspeech audio signals, such as in a recognition task. To find out how similar nonspeech signals are to speech, we measure the closeness between target nonspeech signals and d...

Categorization and discrimination of nonspeech sounds: Differences between steady-state and rapidly-changing acoustic cuesa)

Different patterns of performance across vowels and consonants in tests of categorization and discrimination indicate that vowels tend to be perceived more continuously, or less categorically, than consonants. The present experiments examined whether analogous differences in perception would arise in nonspeech sounds that share critical transient acoustic cues of consonants and steady-state spe...
