Ivbiosakon 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/.

	Front	Central		Back
		unrounded	rounded	unrounded	rounded
Close	i				u
Close-mid	e			ɤ	o
Open-mid	ɛ	ɜ	ɞ	ʌ	ɔ
Open	æ	a	ɶ	ɑ	ɒ

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		n				ŋ
Plosive	p	b	t	d	t͡ɕ	d͡ʑ	k	ɡ	k͡p	ɡ͡b
Fricative	f	v	s	z	ɕ	ʑ	x	ɣ
Trill		ʙ		r
Approximant		ʋ		ɹ		j		ɰ	ʍ	w	h
