# Ivbiosakon language

Ivbiosakon, or Aoma, is an Edoid language of Edo State, Nigeria. The dialect names Ora and Emai are also used for the language.

## 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/.

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 | |
| Fricative | f v | s z | | x ɣ | | |
| Trill | | r | | | | |
| Approximant | | ɹ | j | | w | h |
