Kemezung (Dumbo, Dumbu, Dzumbo, Kumaju) is a Southern Bantoid (Eastern Beboid) language of Cameroon.
According to Ethnologue, it's 85% lexically similar to Bebe.
[2] Cox also claims Kemezung has labialized, palatalized, and prenasalized consonants but does not list all of them.
[5] There are three level tones (high, mid, and low), three falling tones (high-low, mid-low, and long mid-low), and one or two rising tones (low-mid and possibly mid-high).
