Which tribal peoples of Odisha traditionally speak Dravidian languages?

In the state of Odisha, the principal tribal peoples who traditionally speak Dravidian languages are the Khond, Gond, and Oraon (also known as Kurukh) peoples.1

Among these, the Khond people are particularly notable for their use of Kui and its southern dialect, Kuwi, both of which belong to the Dravidian language family. While these groups have historically maintained their own linguistic traditions, many tribal communities in Odisha have increasingly adopted Odia as their primary language due to long-standing contact with neighboring populations and the broader process of acculturation.21
