Adzera (also spelled Atzera, Azera, Atsera, Acira) is an Austronesian language spoken by about 30,000 people in Morobe Province, Papua New Guinea.
The diphthongs /ɑi ɑu/ occur, while other sequences of vowels are split over two syllables.
/h/ occurs in only one word: the interjection hai "yes".
The prenasalized consonants tend to lose prenasalization initially and after consonants.
/tʃ ⁿtʃ/ are sometimes realized as [ts ⁿts], especially in codas.
