The three dialects described here are Hmong Daw (also called White Miao or Hmong Der), Mong Leeg (also called Blue/Green Miao or Mong Leng), and Dananshan (Standard Chinese Miao). Hmong Daw and Mong Leeg are the two major dialects spoken by
Hmong Americans. Although mutually intelligible, the dialects differ in both lexicon and certain aspects of phonology. For instance, Mong Leeg lacks the voiceless/aspirated of Hmong Daw (as exemplified by their names) and has a third nasalized vowel, ; Dananshan has a couple of extra diphthongs in native words, numerous Chinese loans, and an eighth tone.
Vowels The vowel systems of Hmong Daw and Mong Leeg are as shown in the following charts. (Phonemes particular to Hmong Daw and Mong Leeg are color-coded and indicated by a dagger or double dagger respectively.) • 1st Row: IPA, Hmong RPA • 2nd Row: Nyiakeng Puachue • 3rd Row: Pahawh The Dananshan standard of China is similar. Phonemic differences from Hmong Daw and Mong Leeg are color-coded and marked as absent or added. Dananshan occurs only after non-palatal affricates, and is written , much like Mandarin Chinese. is pronounced after palatal consonants. There is also a triphthong , as well as other i- and u-initial sequences in Chinese borrowings, such as .
Consonants Hmong makes a number of phonemic contrasts unfamiliar to English speakers. All non-glottal stops and affricates distinguish aspirated and unaspirated forms, and most also distinguish
prenasalization independently of this. The consonant inventory of Hmong is shown in the chart below. (Consonants particular to Hmong Daw and Mong Leeg are color-coded and indicated by a dagger or double dagger respectively.) • 1st Row: IPA, Hmong RPA • 2nd Row: Nyiakeng Puachue • 3rd Row: Pahawh The Dananshan standard of China is similar. (Phonemic differences from Hmong Daw and Mong Leeg are color-coded and marked as absent or added. Minor differences, such as the voicing of prenasalized stops, or whether is an affricate or is velar, may be a matter of transcription.) Aspirates, voiceless fricatives, voiceless nasals, and glottal stop only occur with
yin tones (1, 3, 5, 7). Standard orthography is added in
angled brackets. The glottal stop is not written; it is not distinct from a zero initial. There is also a , which occurs only in foreign words. The status of the consonants described here as single phonemes with
lateral release is controversial. A number of scholars instead analyze them as biphonemic clusters with as the second element. The difference in analysis (e.g., between and ) is not based on any disagreement in the sound or pronunciation of the consonants in question, but on differing theoretical grounds. Those in favor of a unit-phoneme analysis generally argue for this based on distributional evidence (i.e., if clusters, these would be the only clusters in the language, although see below) and dialect evidence (the laterally released dentals in Mong Leeg, e.g. , correspond to the voiced dentals of White Hmong), whereas those in favor of a cluster analysis tend to argue on the basis of general phonetic principles (other examples of labial phonemes with lateral release appear extremely rare or nonexistent). Some linguists prefer to analyze the prenasalized consonants as clusters whose first element is . However, this cluster analysis is not as common as the above one involving . Only used in
Hmong RPA and not in
Pahawh Hmong, since Hmong RPA uses

b = , but in Pahawh Hmong, it is just "" (3rd-Stage Version).
Syllable structure Hmong
syllables have simple structure: all syllables have an
onset consonant (except in a few particles),
nuclei may consist of a monophthong or diphthong, and the only
coda consonants that occur are nasals. In Hmong Daw and Mong Leeg, nasal codas have become nasalized vowels, though they may be accompanied by weakly articulated . Similarly, a short may accompany the low-falling
creaky tone. Dananshan has a syllabic (written ) in Chinese loans, such as 'two' and 'child'.
Tones Hmong is a
tonal language and makes use of seven (Hmong Daw and Mong Leeg) or eight (Dananshan) distinct
tones. The Dananshan tones are transcribed as pure tone. However, given how similar several of them are, it is likely that there are also phonational differences as in Hmong Daw and Mong Leeg. Tones 4 and 6, for example, are said to make
tenuis plosives
breathy voiced (), suggesting they may be breathy/murmured like the Hmong
g-tone. Tones 7 and 8 are used in early Chinese loans with
entering tone, suggesting they may once have marked checked syllables. Because voiceless consonants apart from tenuis plosives are restricted to appearing before certain tones (1, 3, 5, 7), those are placed first in the table: So much information is conveyed by the tones that it is possible to speak intelligibly using musical tunes only; there is a tradition of young lovers communicating covertly playing a
Jew's harp to convey vowel sounds. ==Orthography==
