Aka, also known as Yaka or Beka, is a Bantu language spoken in the Central African Republic and Republic of Congo, along the Ubangi River dividing the two countries.
Aka is spoken by the Aka people, pygmies closely related to the Ubangian-speaking Baka of Cameroon, Congo and Gabon. Together, these peoples are known as the Mbenga (Bambenga) or Binga (Babinga), the latter derogatory.
The Aka or Biaka (also Bayaka, Babenzele) are a nomadic Mbenga pygmy people. They live in south-western Central African Republic and in northern Republic of the Congo. They are related to the Baka people of Cameroon, Gabon, northern Congo, and southwestern Central African Republic.
Unlike the Mbuti pygmies of the eastern Congo (who speak only the language of the tribes with whom they are affiliated), the Aka speak their own language along with whichever of the approximately 15 Bantu peoples they are affiliated.
