Phonology
The three dialects described here are known as Hmong Daw (also called White Miao or Hmong Der), Mong Njua (also called Blue or Green Miao or Mong Leng), and Dananshan (Standard Chinese Miao). Hmong Daw and Mong Njua are the two major dialects spoken by Hmong Americans. While mutually intelligible, the dialects differ in both lexicon and certain aspects of phonology. For instance, Mong Njua lacks the voiceless/aspirated /m̥/ of Hmong Daw (as exemplified by their names) and has a third nasalized vowel, /ã/; Danashan has a couple extra diphthongs in native words, numerous Chinese loans, and an eighth tone.
For comparison with another Hmongic language, see Hmu, the Chinese standard for Miao.
