Attempts to account for many of the differences between vowels and consonants and between speech and nonspeech, in terms of the range of the contexts in which they are set. Explanations of the different overall levels of discriminability in vowels and consonants in various tasks in terms of their "encodedness" are replaced by a general model…

Examines the auditory evoked potentials (AEP) in the left and right hemispheres of the brain in response to variations in voice onset time (VOT) differences within and between phoneme categories. Subjects were 12 preschool children. (BD)

Administered phonological awareness and phoneme identification tasks to dyslexic children and chronological age (CA) and reading-level (RL) comparison groups. Found no real differences in categorical perception between dyslexic and RL groups; however, more dyslexics (7 of 25) had abnormal identification functions. Results suggest that some…

Argues that phonemes play a central role in speech recognition. Presents simulations showing how the recognition of nonsense syllables can be very well predicted from the recognition of their component phonemes. Suggests that a model in which syllables are factored into their phonemes can account for the results of multidimensional phonetic…

Auditory and auditory-visual (AV) speech perception skills were examined in adults with and without language-learning disabilities (LLD). The AV stimuli consisted of congruent consonant-vowel syllables (auditory and visual syllables matched in terms of syllable being produced) and incongruent McGurk syllables (auditory syllable differed from…

Although developmental increases in the size of the position effect within a mispronunciation detection task have been interpreted as consistent with a view of the lexical restructuring process as protracted, the position effect itself might not be reliable. The current research examined the effects of position and clarity of acoustic-phonetic…

THIS PAPER WRITTEN IN FRENCH, PRESENTS A HYPOTHESIS CONCERNING THE DECODING OF SPEECH IN SECOND LANGUAGE LEARNING. THE THEORETICAL BACKGROUND OF THE DISCUSSION CONSISTS OF WIDELY ACCEPTED LINGUISTIC CONCEPTS SUCH AS THE PHONEME, DISTINCTIVE FEATURES, NEUTRALIZATION, LINGUISTIC LEVELS, FORM AND SUBSTANCE, EXPRESSION AND CONTENT, SOUNDS, PHONEMES,…

The relationship between intraphonemic perception and identification of distorted /r/ was tested using nine graduate students in speech-language pathology with no known speech or hearing disorders. Laboratory training was found not to improve the identification of distorted /r/. Identification ability was related more to discrimination of /t-d/…

This study aimed to (a) investigate the effect of using a hearing aid in conjunction with a cochlear implant in opposite ears on speech perception in quiet and in noise, (b) identify the speech information obtained from a hearing aid that is additive to the information obtained from a cochlear implant, and (c) explore the relationship between…

Investigates the principles underlying the perception of vowel stimuli. The results support Chistovich's claim. When judging the distance between synthetic vowel stimuli, speakers refer to the phonemic structure of their native language. They determine the phonemes closest to the stimuli and then compare the phonemes and not the stimuli…

Findings indicated that the speech training program significantly improved the auditory speech perception of the hearing impaired Ss. (DLS)

Notes that phonemic restoration is a powerful auditory illusion. Points out that when part of an utterance is replaced by another sound, listeners perceptually restore the missing speech. Several paradigms measure this illusion and explore its bottom-up and top-down bases. Findings reveal that acoustic properties of the replacement sound strongly…

Compression hearing aids have the inherent, and often adjustable, feature of release time from compression. Research to date does not provide a consensus on how to choose or set release time. The current study had 2 purposes: (a) a comprehensive evaluation of the acoustic effects of release time for a single-channel compression system in quiet and…
