A Comparison of phonological processing and Dezfuil dialect of Persian language in the framework of Optimality Theory

The purpose of this paper is the description and analysis of the most frequent phonological processes in Dezfuli dialect as well as their use within the Optimality approach which is the new theory in phonology and it is also constraint–based approach, since the research in the framework of optimality is analyzed, the present study was conducted with a choice of analytical method and to collect samples and data from field work and then collected the recorded fifteen hours conversations of normal speech of informants and participants have the average age between thirty to fifty–five years. In addition, one of the writers is a native speaker of this dialect. The present study utilizes discrete mechanisms respectively. After collecting this data, voice transcription and classification has been done. The most active processes in this dialect, the vowel conversion process, vowel harmony, eliminating assimilation are studied. According to the study, the maximum markedness optimal constraints in Dezfuli dialect are dominant. Compared to the standard Persian, faithfulness constraints dominated in the hierarchy restrictions on the rest of the samples. As well as the processes of elimination and assimilation are the most active than other processes in this dialect
