The consonant inventory of the Làng Lỡ dialect, as cited by Michel Ferlus:
There are eight tones in the Làng Lỡ. Tones 1 to 6 are found on sonorant-final syllables (a.k.a. 'live' syllables): syllables ending in a vowel, semi-vowel or nasal. Tones 7 and 8 are found on obstruent-final syllables (a.k.a. 'stopped' syllables), ending in -p -t -c -k. This is a system comparable to that of Vietnamese.
