The aim of the present paper is to study the status of the short vowels /i/ and /u/ in five selected Iranian Balochi dialects. These dialects are spoken in Sistan (SI), Saravan (SA), Khash (KH), Iranshahr (IR), and Chabahar (CH) regions located in province Sistan va Baluchestan in the southeast of Iran. This study investigates whether these two vowels have the same qualities as the short /i/ and /u/ do in the Common Balochi inventory (i, iː, u, uː, a, aː, eː, oː). The Common Balochi inventory is the vowel system represented generally for Balochi language, which is a North-Western Iranian language, a sub-branch of the Indo-Iranian family. The data for this survey are gathered from villages, rural areas, and cities in these regions in the forms of free speech and verbal elicitation from more than 20 literate and non-literate male and female language consultants, 2 males and 2 females for each dialect. The investigation reveals that the short /i/ and /u/ show strong tendencies towards a lower position. This study suggests phonemic systems in which the short /i/ is modified to short /e/ in all dialects, but /u/ is modified to /o/ only in SI, SA, and CH; the lowering of the short /u/ to short /o/ in KH and IR may still be in the transition stage. It is possible that Persian, as the dominant language has had its influence on these dialects causing a lowering tendency in the two vowels under study.

This article provides an overview of natural phonological processes in the dialect of Sistani Persian spoken in Iranian Sistan, and reviews theoretical implications of these processes. A representative selection of processes in the language is examined in reference to conditioning by surrounding segments and conditioning in reference to syllable structure. While assimilation and dissimilation are tied to segmental context, deletion, epenthesis and metathesis are considered in light of syllable structure requirements. Synchronically, natural processes include those that are of an allophonic nature as well as those which involve morphophonological alternation. The description of these phenomena is corroborated by a discussion of the application of natural processes in diachronic changes. The authors show that, in some cases, the Sonority Sequencing Principle (SSP) is violated in Sistani Persian. This phenomenon is attributed not to language-internal factors, but rather to the generalization of marked structures as a result of interference from Standard Persian.

This study was set out to shed light on the efficacy of pushed output directed by scaffolding on 41 (24 female and 17 male) upper-intermediate EFL learners’ speaking fluency and accuracy. A public version of IELTS speaking test was held to measure learners’ entrance behavior. Then, they were randomly assigned into symmetrical, asymmetrical, and control group. The experimental and control groups covered 7 lessons of New Interchange 2 during 15 sessions, twice a week for about 45 minutes each session. Control group received placebo while symmetrical and asymmetrical groups worked on pushed output tasks. The data were audio recorded and transcribed for statistical analyses. The results indicated the efficacy of pushed output in boosting speaking. However, tests of between-subjects effects revealed that the mean score of the control group was not significantly different from that of experimental groups concerning speaking fluency. Furthermore, the results of Tukey's HSD post-hoc tests showed that asymmetrically pushed output activities were more effective in enhancing learners speaking accuracy. In sum, the results suggested that the implementation of pushed out put strategies in student centered contexts could be considered as an effective way in the development of learners’ oral output.
