This study aims to analyze the correlation between ictus and acoustic features of duration, intensity and pitch in Persian folk poems. For this purpose, 51 lines of Persian folk poems were recorded, which consisted of 139 syllables in ictus positions and 139 syllables in off-ictus positions. Each line was segmented into syllables, feet and colons. The vowels in ictus and off-ictus positions were analyzed acoustically and the amounts of pitch, intensity and duration of vowels were measured manually. In order to compare the acoustic features of these vowels, Some Paired two-sample t-test were conducted. The results suggested that: a) duration of vowels in ictus positions is more than that of vowels in off-ictus positions. In addition, analytic statistics showed that the effect of ictus on the duration of vowels is significant; b) the mean intensity of vowels in ictus positions is less than that of vowels in off-ictus positions. Furthermore, analytic statistics indicated that the effect of ictus on the intensity of vowels is significant and c) the vowels in off-ictus positions have lower pitch values than those in ictus positions. Moreover, it was declared that the effect of ictus on the pitch value of vowels is not significant.

Abstract
The purpose of the present study is to explore the process of vowel reduction in Kermani accent. The process of vowel reduction occurs in unstressed syllables which shifts vowels toward other vowels. In this study, 5 male and 5 female native speakers of Kermani accent, pronounced 24 words in 3 repetitions ...

The purpose of the present study is to explore the process of vowel reduction in Kermani accent. The process of vowel reduction occurs in unstressed syllables which shifts vowels toward other vowels. In this study, 5 male and 5 female native speakers of Kermani accent, pronounced 24 words in 3 repetitions containing six simple vowels in stressed and unstressed syllables. The participants’ productions were recorded using Shure microphone and were analyzed using Praat software (Ver. 5.2.24). A text grid was made for each word. Then, duration, F1, F2 and F0 of vowels were measured and compared in stressed and unstressed syllables. Overall, the obtained results confirmed that the duration and F0 of vowels decreases in unstressed syllables and the amount of F1 of all the vowels and the F2 of the vowels [ɑ, e, o, u] have a tendency towards the F1 and F2 of /ǝ/. Results also indicated that the process of vowel reduction is centripetal in Kermani accent.
