Boazi language
Boazi (Bwadji), also known as Kuni after one of its dialects, is a Papuan language spoken in the Western Province of Papua New Guinea by the Bwadji people in the vicinity of Lake Murray and is written using the Latin script, with  for ,  for , and  for (relatively infrequent) vowel length. Some recordings of songs and stories have been made in this language.

Phonology 

 /l/ can fluctuate as sounds [l ~ d ~ ɾ]. Sounds [ɾ] and [d] are more common in word-medial positions.
 /q/ may also be heard as a retracted velar plosive [k̠] in free variation.
 /ᶰq/ can also be heard as a prenasal velar fricative [ᵑɣ] in free variation.
 Sounds /s, z/ tend to become alveolo-palatal [ɕ, ʑ] when in the environment of a high vowel.
 Sounds /v, z/ tend to be devoiced [v̥, z̥] in word-final positions.
 /f/ may be heard in free fluctuation with [θ] within the environment of a high vowel.
