Phonology

Aoma has a rather reduced system, compared to proto-Edoid, of seven vowels; these form two harmonic sets, /i e a o u/ and /i ɛ a ɔ u/.^[2]

It has only one clearly phonemic nasal stop, /m/; [n] alternates with [l], depending on whether the following vowel is oral or nasal. (The other approximants, /ɹ j w h/, are also nasalized in this position: see Edo language for a similar situation.) The inventory is:^[3]
