Normal and dyslexic right-handed children were assessed with three dichotic listening tests, the Dichotic Digits test, the Competing Words subtest of the SCAN, and the Dichotic Consonant-Vowel test. Performance was measured as both number and percentage of correct responses in the right and left ears. Laterality was defined as a simple difference in percentage between the two ears. Differences ...

Earlier work [Nittrouer et al., J. Speech Hear. Res. 32, 120-132 (1989)] demonstrated greater evidence of coarticulation in the fricative-vowel syllables of children than in those of adults when measured by anticipatory vowel effects on the resonant frequency of the fricative back cavity. In the present study, three experiments showed that this increased coarticulation led to improved vowel rec...

This study was an attempt to investigate the effect of vowel-recognition training on beginner and advanced Iranian ESL learners. A total of 36 adult Iranian ESL learners (18 advanced and 18 beginners) who were students of various majors at Memorial University (MUN) were recruited for the study. Advanced participants had the experience of living in Canada for at least three years while beginners...

PURPOSE Temporal order abilities decrease with age. Declining temporal processing abilities may influence the identification of rapid vowel sequences. Identification patterns for asynchronous vowel pairs were explored across the life span. METHOD Young, middle-aged, and older listeners completed temporal order tasks for pairs of 70-ms and 40-ms vowel stimuli. For a given vowel duration, natur...

In this paper, the acoustic correlates of the labial and alveolar place of articulation for both plosive and fricative consonants are investigated, and the results are analyzed in terms of vowel context, voicing and manner of articulation. Several measurements, including formant and noise measurements, are reported for CVs spoken by two male and two female talkers. It was found that the spectra...
