Buying guides
What should global AI teams know about buying Indian language data?
Updated 2026-08-01 · 4 min read
Short answer
Three things change when a global team buys Indian data. First, 'Hindi' is not a market — India is a dozen language markets with different dialect structures and different amounts of existing data. Second, code-mixing with English is the default in urban speech, so monolingual specifications produce corpora that do not match usage. Third, consent, data residency and IP need to be specified against Indian law and your own regulator's expectations at the same time. Working with one partner who runs recruitment, recording and annotation avoids the coordination cost of contracting separately in each state.
Key takeaways
- Specify per language and per dialect, not 'Indian languages'.
- Assume code-mixing unless your users are rural and monolingual.
- Contract for consent, residency and IP in one document, not three.
India is many markets
Language boundaries do not follow state lines cleanly, dialect variation within a language is often larger than the difference between neighbouring languages, and the amount of usable public data varies by an order of magnitude between them.
Time zones and review cycles
Rolling batch delivery with a fixed weekly review slot works better than milestone handovers across a ten-hour time difference. The constraint is usually review latency on the buyer's side.
Compliance in two directions
The corpus must satisfy Indian personal-data rules and whatever your own jurisdiction requires of training data provenance. Write both into the specification rather than discovering the conflict at delivery.
One partner or many
Contracting studios directly in each state is cheaper on paper and expensive in practice, because QA consistency across vendors becomes your problem. A single scope with one QA standard is what makes multi-state data interchangeable.
