Vowels

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.

Why this record matters
The phrase “austroasiatic language spoken in Southeast Asia” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 6, 2026. The linked authority identifier is Q3380501. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
