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, {{IPA|/i e a o u/}} and {{IPA|/i ɛ a ɔ u/}}.Archangeli & Pulleyblank, 1994. Grounded phonology, p 181ff
It has only one clearly phonemic nasal stop, {{IPA|/m/}}; {{IPA|[n]}} alternates with {{IPA|[l]}}, depending on whether the following vowel is oral or nasal. (The other approximants, {{IPA|/ɹ j w h/}}, are also nasalized in this position: see Edo language for a similar situation.) The inventory is:Jeff Mielke, 2008. The emergence of distinctive features, p 136ff;
also found in Variation and gradience in phonetics and phonology, p 26ff
