Lanoh includes Sabüm and Semnam as subgroups (Burenhult and Wegener 2009).
'Lanoh' is the official Malaysian label for a number of Central Aslian varieties in the Perak valley, but only speakers of some of these refer to themselves as Lanoh. There is no other label for this group as a whole. Varieties/dialects include Jengjeng, Kobak, Sabüm, Semnam, and Yir. Of these, only Semnam is still spoken on a daily basis (c. 300 speakers).
