Ivbiosakon, or Aoma, is an Edoid language of Edo State, Nigeria. The dialect names Ora and Emai are also used for the language.
Aoma has a rather reduced system, compared to proto-Edoid, of seven vowels; these form two harmonic sets, pronounced as //i e a o u// and pronounced as //i ɛ a ɔ u//.[1]
It has only one clearly phonemic nasal stop, pronounced as //m//; pronounced as /[n]/ alternates with pronounced as /[l]/, depending on whether the following vowel is oral or nasal. (The other approximants, pronounced as //ɹ j w h//, are also nasalized in this position: see Edo language for a similar situation.) The inventory is:[2]
