Phonology

Mapos Buang has a larger sound inventory than is typical of most Austronesian languages.^{[citation needed]} 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.

Vowels

	Front	Central	Back
High	i(ː)		u(ː)
Mid	e(ː) ⟨ë⟩	ə* ⟨e⟩	o(ː)
Low	ɛ(ː) ⟨e⟩	a(ː)	ɔ(ː) ⟨ö⟩

* [ə] is a prominent feature of Buang phonology, but is not contrastive. Thus both it and [e] are represented with ⟨e⟩.

Vowel length is shown in the orthography by doubling the letter.

*/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. /β/ is a voiced bilabial fricative.

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