Mapos Buang has a larger sound inventory than is typical of most Austronesian languages.{{citation needed|date=November 2020}} Notable is the existence of a phonemic contrast between a velar nasal and a uvular nasal, which is extremely rare among the world's languages. Along with this, its phonology is unusually symmetrical compared to most other languages.

* {{IPA|[ə]}} is a prominent feature of Buang phonology, but is not contrastive. Thus both it and [e] are represented with {{Angbr|e}}.

Vowel length is shown in the orthography by doubling the letter.{{Cite web |date=2022-09-15 |title=Mapos Buang dictionary |url=https://www.sil.org/resources/archives/31034 |access-date=2023-02-15 |website=SIL International |language=en}}

*{{IPA|/w/}} is a bilabial approximant or semivowel with no co-articulated velar component. It is placed in the labio-velar series of the chart as it fills a gap in this position. {{IPA|/β/}} is a voiced bilabial fricative.

Orthography is the same as in the IPA when nothing is shown.
