The documentation of Bati language and oral traditions aims at creating a repository of language and cultural data representative of the five varieties spoken in the Bati Canton, in the Littoral region of Cameroon. Number of Bati speakers is estimated at 800. The resulting corpus will lay the empirical ground for cross-dialectal studies in linguistics and others fields in the humanities such as anthropology, which will better inform on the bi-vectorial dynamics of Bati language and identity, torn as they are, between the Mbam and the Basaa groups respectively.
