Visual speech information aids elderly adults in stream segregation
Listening to a speaker while hearing another speaker talks is a challenging task for elderly listeners. We show that elderly listeners over the age of 65 with various degrees of age-related hearing loss benefit in this situation from also seeing the speaker they intend to listen to. In a phoneme monitoring task, listeners monitored the speech of a target speaker for either the phoneme /p/ or /k...
متن کامل[Effect of stimulus intensity on visual stream segregation].
Two experiments were performed to examine the effect of stimulus intensity on VISS (visual stream segregation) which is a kind of beta movement first described by Bregman and Achim (1973). Six subjects were required to find the upper threshold of ISI for producing VISS under various conditions of the stimulus intensity in each experiment. The ISI threshold decreased as the stimulus intensity wa...
متن کاملStream segregation in the anesthetized auditory cortex
Auditory stream segregation describes the way that sounds are perceptually segregated into groups or streams on the basis of perceptual attributes such as pitch or spectral content. For sequences of pure tones, segregation depends on the tones' proximity in frequency and time. In the auditory cortex (and elsewhere) responses to sequences of tones are dependent on stimulus conditions in a simila...
متن کاملA new speech enhancement: speech stream segregation
Speech stream segregation is presented as a new speech enhancement for automatic speech recognition. Two issues are addressed: speech stream segregation from a mixture of sounds, and interfacing speech stream segregation with automatic speech recognition. Speech stream segregation is modeled as a process of extracting harmonic fragments, grouping these extracted harmonic fragments, and substitu...
متن کاملEffects of context on auditory stream segregation.
The authors examined the effect of preceding context on auditory stream segregation. Low tones (A), high tones (B), and silences (-) were presented in an ABA- pattern. Participants indicated whether they perceived 1 or 2 streams of tones. The A tone frequency was fixed, and the B tone was the same as the A tone or had 1 of 3 higher frequencies. Perception of 2 streams in the current trial incre...
