Mpiemo (Bimu) is a Bantu language of the Central African Republic. The Atlas linguistique du Cameroun (ALCAM, or "Linguistic Atlas of Cameroon") gives the name Mpo.
There is little description of the language, but one team used Mpiemo data to test the ability of computer programs to analyze real language data.
