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...

Speaking rate is thought to affect the spectral features of vowels. Target-undershoot models of vowel production predict more spectral reduction and coarticulation of vowels in fast-rate speech than in normal-rate speech. To test this prediction, a meaningful Dutch text of about 850 words was read twice by an experienced newscaster, once at a normal speaking rate and once as fast as possible. A...

This article is concerned with the acoustic correlates that characterize stress and accent in Catalan and Spanish. We analyzed four acoustic correlates of stress (syllable duration, vowel quality, overall intensity, and spectral balance) in four conditions, namely, stressed and unstressed syllables in both accented and unaccented environments. This allowed us to examine the relative strength of...

Discharge patterns produced by fibres from normal and impaired auditory nerves in response to speech and other complex sounds can be discriminated subjectively through visual inspection. Similarly, responses from auditory nerves where speech is presented at diminishing sound levels progressively deteriorate from those at normal listening levels. This paper presents a Neurogram Similarity Index ...

This study explores whether there is an asymmetry with respect to the perceptual salience of an increase vs. a decrease of phonologically relevant features. A forced-choice discrimination experiment was conducted on stimulus pairs that included one member with unchanged phonetic features and the other with either increased or decreased degree of features (i.e., vowel nasality or VOT). The resul...
