Two varieties, Alumu and Tesu, differ only in intonation.[1] Information for Alumu and Tesu is listed from Blench (2004).[2]
Alumu (or Arum), with 4,000 speakers, is spoken in the settlements of Arum-Kado (main settlement), Arum-Tsabo, Arum-Sarki, Arum-Tumara, Arum-Chugbu, Arum-Kurmi (Gbira), and Arum-Chine.
Tesu (Təsu) (Hausa: Chessu[3]), with just under 2,000 speakers, is spoken in the two villages of Chessu Sarki and Chessu Madaki, which are about one kilometre apart from each other on the Wamba - Fadan Karshi road.
Akpondu is also closely related (also Babur, Nisam and Nigbo) but moribund or extinct, and its classification as a separate language or as a shifting dialect or sociological group of related dialects is not clear.[4]
