چکیده
In face-to-face conversation speech is perceived by ear and eye. We studied the prerequisites of audio-visual speech perception by using perceptually ambiguous sine wave replicas of natural speech as auditory stimuli. When the subjects were not aware that the auditory stimuli were speech, they showed only negligible integration of auditory and visual stimuli. When the same subjects learned to perceive the same auditory stimuli as speech, they integrated the auditory and visual stimuli in a similar manner as natural speech. These results demonstrate the existence of a multisensory speech-specific mode of perception.

متن کاملThe Effect of Combined Sensory and Semantic Components on Audio–Visual Speech Perception in Older Adults
Previous studies have found that perception in older people benefits from multisensory over unisensory information. As normal speech recognition is affected by both the auditory input and the visual lip movements of the speaker, we investigated the efficiency of audio and visual integration in an older population by manipulating the relative reliability of the auditory and visual information in...
متن کاملAge-related experience in audio-visual speech perception
The current study addresses the changing use of audio and visual cues in audio-visual speech perception during adulthood by testing young and middle-aged adults using stimuli with incongruent audio-visual consonants. Young adults gave more audio responses and fewer visual responses than middle-aged adults. Results show no age differences in auditory or visual sensitivity. The discrepancy in use...
متن کاملThe visual perception of lexical tone
Visual speech (lipreading) supports speech perception not only when the auditory signal is limited, degraded, or miss-ing, but also in mismatched auditory and visual speech component conditions when the auditory signal is clear and undegraded. While most of this research has been done with segments (consonants and vowels), research at MARCS has now provided evidence for visual speech cues for n...
متن کاملSeeing to hear better: evidence for early audio-visual interactions in speech identification.
Lip reading is the ability to partially understand speech by looking at the speaker's lips. It improves the intelligibility of speech in noise when audio-visual perception is compared with audio-only perception. A recent set of experiments showed that seeing the speaker's lips also enhances sensitivity to acoustic information, decreasing the auditory detection threshold of speech embedded in no...
