Mok language
Mok (/mɔ̀k/ ‘mountain people’), also known as Amok, Hsen-Hsum, and Muak, is an Angkuic language or dialect cluster spoken in Shan State, Myanmar

7 speakers in Lampang province, Thailand were reported by Wurm & Hattori (1981). Varieties
Hall & Devereux (2018) report that five varieties of Mok are spoken in Shan State, Myanmar, providing the following comparative vocabulary table. These varieties have some lexical similarity (the lowest being 88%) with each other, but very low lexical similarity with the other Angkuic languages. Owen (2018) names these varieties Hwe Law, Chieng Kham, Pha Lam, Punglong, and Hwe Koi. A Mok dialect of Shan State has been documented by Shintani (2019). Geographic distribution 
Tannumsaeng (2020) describes three locations for Mok: between Mong Khet and Mong Yang and south of Kengtung in Myanmar, and on the Thai-Burmese border in Chiang Rai Province, Thailand. The main Mok-speaking areas in Shan State include an area just to the south of Kengtung, and another area situated between Mong Khet and Mong Yang. Phonology 
Tannumsaeng (2020), citing Hall & Devereux (2018), provides the following phonology for Mok. The consonants are /pʰ p m f w tʰ t n s l r c ɲ j kʰ k ŋ ʔ h/, with reduced /m̩ n̩ ɲ̩ ŋ̩ pə tə kə sə/. /f/ and /r/ only appear in certain varieties. The vowels are /i e ɛ u ɯ o ɤ ɔ a/, with the diphthongs /ia ɯa ua/. Mok has two tones, one low and one high. References and notes
