Kubu is a Malayic language spoken in the southern swamps of the island of Sumatra in Indonesia by the Kubu people (Orang Rimba), many of whom are nomadic.
There is a degree of dialectal diversity.
In Bukit Duabelas (Jambi), the Rimba language is very glottal, which initially makes it difficult to understand.
[2] Some of the variations in Kubu isolects have been presented by Dunggio.
