Abesabesi – often referred to as Akpes in literature – is a minority language spoken by approximately 7,000 people in southwestern Nigeria. A gradual shift towards the regional lingua franca Yoruba is favored by rapid urbanization and unfavorable language attitudes. This project is based in the town Ikeram (Ondo State) to document the language and create an audio-visual corpus with time-aligned transcriptions. The corpus feeds into an electronic reference grammar of the Abesabesi language, which will be developed as a case study.
