Ngombe includes several dialects in addition to Ngombe proper (Ŋgɔmbɛ). These are Wiindza-Baali, Doko (Dɔkɔ), and Binja (also rendered Binza, Libindja, or Libinja). The latter is not the same as the Binja/Binza language. Binja dialect is primarily spoken in Orientale Province and Aketi Territory, and shares about three-quarters of its linguistic characteristics with standard Ngombe. Maho (2009) lists Doko as a distinct language in a separate group.
