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...

this paper addresses the validity of two hypotheses concerning changes of vowel quality in persian. the theory of centralization claims that there is a strong correlation between vowel duration and vowel quality. as vowel duration is shortened in unstressed contexts, the size of the vowel inventory reduces toward the center, leading to considerable overlap between different categories and a red...

the changing of round and back vowel /u/ to unround and front vowel [i] occurs in lori dialects as well as some other persian dialects. this vowel change includes both unrounding and fronting. this paper aimed at coming up with an inclusive ranking of constraints to explain occurrence and nonoccurrence of this vowel change in various phonological environments in silahkori dialect within optimal...

In this article, the low back vowel /A/ in word-final positions in Eghlidian dialect, one of Persian dialects, is studied. This vowel is represented phonetically as [A], [o] and [@] in different phonetic environments. Therefore many words were collected via interviewing ten native speakers so that these different alternant forms can be accounted for appropriately. Since one of the authors of th...

This paper reports the results of an experimental study on non-native production of English vowels. Two groups of Persian EFL learners varying in language proficiency were tested on their ability to produce the nine plain vowels of American English. Vowel production accuracy was assessed by means of acoustic measurements. Ladefoged and Maddison’s (1996) F1 F2 measurements for American English v...

this study examines the phonetic properties of lexical stress in english produced by persian speakers learning english as a foreign language. the four most reliable phonetic correlates of english lexical stress, namely fundamental frequency, duration, intensity, and vowel quality were measured across persian speakers’ production of the stressed and unstressed syllables of five english disyllabi...

In this paper we analyzed some of the phonological rules of Russian loanword adaptation in Persian, on the view of Optimal Theory (OT) (Prince and Smolensky, 1993, 2003). It is the first study of phonological process on Russian loanwords adaptation in Persian. By gathering about 50 current Russian loanwords, we selected some of them to analyze. We found out that vowel insertion, vowel prothesis...

this article addresses the perceptual correlates of compensatory lengthening in persian. in a perception experiment, duration, spectral tilt measurements h1-h2 and h1-f1 and f0 were varied in several steps based on the results from a production experiment (sadeghi, 2007). subjects were asked to identify the tokens involving vowel length. results revealed that duration is the most reliable perce...
