Perception of overlapping syllables
نویسنده
چکیده
Some experiments have been performed in which the perception of two consonant-vowel syllables, the starting time of one was delayed relative to the other, have been studied. The consonant was /w/ or /j/, the vowel /i/ or /a/, and the fundamental frequency of the syllable 100 or 150 Hz. The delay was varied from 0 ms (simultaneous presentation) to 200 ms (consecutive presentation). As expected, the frequency of hearing both consonants correctly increased as the delay in starting times increased and the amount of overlap decreased. Unexpectantly, however, differences in fundamental frequency appeared to have no effect. With certain degrees of overlap, consonants were perceived which were not present in the physical stimulus.

Evoked cortical activity and speech recognition as a function of the number of simulated cochlear implant channels.
OBJECTIVES (1) To determine if consonant-vowel-consonant (CVC) syllables [Hillenbrand J, Getty L, Clark M, Wheeler K. Acoustic characteristics of American English vowels. J Acoust Soc Am 1995;97:3099-3111] could be used to evoke cortical far field response patterns in humans, (2) to characterize the effects of cochlear implant-simulated channel number on the perception and physiological detecti...
متن کاملLeft temporal lobe dysfunction in schizophrenia: event-related potential and behavioral evidence from phonetic and tonal dichotic listening tasks.
BACKGROUND Asymmetric reduction of the P3 event-related potential (ERP) has provided evidence of left temporal lobe dysfunction in schizophrenia. Prior studies have been limited by reliance on simple target detection (oddball) tasks with pure tones. This study investigated the time course and topography of ERPs to binaural syllables or complex tones in dichotic listening tasks. METHODS Event-...

The goal of the present study is to investigate the degree to which native Japanese speakers’ perception of syllables in spoken English words is affected by various phonetic and phonological factors. Specifically, the present study examined whether Japanese listeners’ perception of English syllables is affected not just by phonological factors such as syllable complexity, but also by acoustic-p...
متن کاملA Production and Perception Study on Tonal Neutralization in Nanchang
In a production study of tonal contrasts in lexically stressed but grammatically stressless syllables vs. lexically stressless syllables in Nanchang, a Gan dialect spoken in the city of Nanchang, Jiangxi province, we found that tonal neutralization only occurs in lexically stressless syllables. We argue that the main phonetic ground for such a tonal contrast distribution lies in the rhyme durat...
متن کاملListening with eye and hand: cross-modal contributions to speech perception.
Three experiments investigated the "McGurk effect" whereby optically specified syllables experienced synchronously with acoustically specified syllables integrate in perception to determine a listener's auditory perceptual experience. Experiments contrasted the cross-modal effect of orthographic on acoustic syllables presumed to be associated in experience and memory with that of haptically exp...
