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/.[2]

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:[3]

  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
