To measure the symmetry of adult categorical phoneme perception, 10 adult male undergraduate students enrolled in an introductory psychology class were the subjects for this study as part of their course requirements. The stimuli used in this study were prepared at Haskins Laboratories by means of a parallel resonance synthesizer and computer. The…

Notes that in phonetic categorization, listeners hear a range of speech sounds forming a continuum of ambiguous sounds between two endpoints and are required to identify the sounds as one or other of the endpoints. Points out that this task has been used in phonetics and in psycholinguistics to study categorical perception, selective adaptation,…

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…

Seventy-six children with cochlear implants completed a nonword repetition task. The children were presented with 20 nonword auditory patterns over a loudspeaker and were asked to repeat them aloud to the experimenter. The children's responses were recorded on digital audiotape and then played back to normal-hearing adult listeners to obtain…

One of the difficulties faced by cochlear implant (CI) recipients is perception of low-intensity speech cues. A. E. Vandali (2001) has developed the transient emphasis spectral maxima (TESM) strategy to amplify short-duration, low-level sounds. The aim of the present study was to determine whether speech scores would be significantly higher with…

This study examined the roles of speech perception and phonological processing in reading and spelling acquisition for native and nonnative speakers of English in the 1st grade. The performance of 50 children (23 native English speakers and 27 native Korean speakers) was examined on tasks assessing reading and spelling, phonological processing,…

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 principal objective of this study was to evaluate, in 21 severely hearing impaired children (9 to 12 years old), the relative effects of length of stimuli by closed set identification tasks. (Author/SBH)

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/…

Examples of pattern cues that are available to profoundly hearing-impaired children are presented through an optical analog, and the usefulness of these cues is shown with regard to vowel and consonant identification, word stress-pattern perception, and distinction among sentences that differ in number of syllables, pattern, intensity, or rate.…

The status and progress of several studies dealing with the nature of speech, instrumentation for its investigation, and instrumentation for practical applications is reported on. The period of January 1 through June 30, 1969 is covered. Extended reports and manuscripts cover the following topics: programing for the Glace-Holmes synthesizer,…

An analysis of rhythm in French. The research project concentrated on two points: the perception of a "click" superimposed on an utterance and the reproduction of the click by a knock simultaneous with the stimulus. Conclusions based on linguistic and non-linguistic aspects are drawn. (Text is in French.) (AMH)
