This paper is an attempt to shed light on the effects of modernization, urbanization, monolingual educational system, and mass media as well as the process of globalization on dialect leveling among Persian dialects. In so doing, the first part of the paper elaborates on the relationship between globalization and sociolinguistics, and on the concept of standardization.
Also, it discusses some factors accelerating dialect leveling among Persian dialects. The second part of the paper presents some empirical evidence for the change, based on the data collected from 3 Persian dialects, namely: Birjandi, Neyshaboori, and Yazdi. Three spoken language sample corpora from two age cohort groups in each speech community were collected.
Having transcribed the data, the researchers juxtaposed the phonological, morphological, and syntactic conventions of the two groups of each speech community for further in-depth analysis. Comparing the speech samples of the two age cohorts in each corpus revealed significant movements towards standard dialect. However, the quality and quantity of the observed movements did not appear to be the same across the dialects in question.
