Rotokas language

Rotokas is a language spoken in Bougainville, an island to the East of Papua New Guinea. Its main claim to fame, linguistically speaking, is that it reputed to possess the world's smallest phonemic inventory: 6 consonants (K,P,R,S,T,V) and 5 vowels (A,E,I,O,U). Only Pirahã has less.

Thus, the Rotokas alphabet consists of the eleven letters AEIKOPRSTUV.
