Abstract—The data of the present article was collected through a randomly classified data collection process and Labovian sociolinguistic interviews; the data, then, was analyzed through the Pearson Chi square method by means of SPSS. The data were described through cross tabulations and diagrams as well. A total of 210 informants were interviewed: there are six groups of informants with different Persian accents (Tehrani, Isfahani, Shirazi, Mashhadi, Baboli and Ardebili), each group covering 35 informants. I followed sociolinguistic research techniques similar to the ones utilized and established in Labov , Milroy , Eckert , Josey  and Oliver Rajan . The hypothesis of the present survey research is that there is a significant difference between and among different groups of informants' accents regarding their use of vowel harmony.
