Comments:

Uzere dialect. Isoko is spoken around the town
of Oleh in Bendel State, Nigeria. Isoko has two level
tones; final L is raised in affirmative declaratives. The
vowels /i,e,o,u/ belong to one harmony set (+ATR) in
opposition to the remainder. A word must have vowels from
one set or the other, except that /a/ may appear in
prefixes before [+ATR] vowels. Clusters with the flap
occur, including h + flap r which has been interpreted as
a voiceless flap by others. Breathy voiced 'v' is tending
to lose its distinctive phonation and merge with /v/.
