This study is a synchronic analysis of Khmer phonological variation which aims to identify sub-dialects spoken in Thailand’s northeastern provinces, focusing on regional variations in initials, vowels, and finals. The findings result in a classification of Khmer into two main groups: a Western Khmer and an Eastern Khmer group, including fifteen sub-dialects within the studied region concerning the overlap on linguistic maps of the initial consonant, vowel, and final consonant.Social SciencesArts and HumanitiesArticleSCOPUS2-s2.0-8521437270726976056
