Mapos Buang has a larger sound inventory than is typical of most Austronesian languages. 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.
* [?] is a prominent feature of Buang phonology, but is not contrastive.
*/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. /?/ is a voiced bilabial fricative.
