Telugu here is instantly identifiable to any Telugu speaker, and for a long time that was a problem. The literary and broadcast standard was codified on delta speech, so the northern register spent a century marked as rustic and became the accent that films reach for when they want a comic servant. What is actually going on is more interesting: this register retains verb forms and vocabulary the standard has dropped, and in the northern mandals it carries a layer of Odia words in ordinary domestic use. The region also produced the most consequential argument in modern Telugu about which speech counts — Gurajada Apparao wrote Kanyasulkam in 1892 in the language people actually spoke, set it in Vizianagaram, and forced the question of whether literature had to be written in a classical register.
Uttarandhra TeluguDravidian, South-Central
Slower vowels, older verb endings retained, and a lexicon that diverges from the delta's in exactly the everyday areas — food, kinship, farming. It is one register, not several, but the Odia share in it rises steadily going north.
Speakers: The majority speech of the plain and the coast
Srikakulam speechDravidian, South-Central
The northernmost variety, with the largest Odia loan layer and the most distinctive intonation. It is the version most often imitated, usually badly, in Telugu cinema.
Odia in the northern mandalsIndo-Aryan, Eastern
Spoken by long-settled households in the belt below the Bahuda, where schooling is available in both languages and most families use both. Their Odia is the Ganjami register, not the coastal standard.
Konda (Kubi) and KuviDravidian, South-Central
Hill languages of the Konda Dora and Kondh communities on the plateau, spoken above a coast that speaks a different branch of the same family.
Savara (Sora) and GadabaAustroasiatic, Munda
Munda languages in the northern ghats, in villages that continue across the state boundary. Their presence is the strongest single argument that this upland is one cultural block cut by an administrative line.
Adivasi OriyaIndo-Aryan contact variety
A simplified Odia used as the market and inter-community language of the agency tracts, in an area administered in Telugu. Almost nobody's mother tongue and almost everybody's second language.
