Phonology

Aoma dialect 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/.

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:

	Labial	Alveolar	Palatal	Velar	Labio-velar	Glottal
Nasal	m	l [n]
Plosive	p  b	t  d		k  ɡ	k͡p  ɡ͡b
