What is translation & localisation data and how does it work?
Updated 2026-08-01 · 4 min read

Short answer
Human translation and parallel-corpus creation across Indian languages, built for machine-translation training and multilingual LLM evaluation rather than for publication. In practice the work runs as glossary and register agreement, then translation by native speakers of the target language, then independent bilingual review, and you receive sentence-aligned parallel data, updated glossary. 2-4 weeks for typical corpus volumes per language pair.
Key takeaways
- Back-translation checks are run on a sample so you can see where source ambiguity, not translator error, causes divergence.
- Typical buyers: MT training, Multilingual LLM eval, Product localisation data.
- Recruitment approach: Translators are native in the target language and screened on domain samples.

Quality control and acceptance
Back-translation checks are run on a sample so you can see where source ambiguity, not translator error, causes divergence.
Failures are remedied by re-collection rather than by editing delivered files, because repaired audio carries artefacts that survive into the trained model.
Who this is for
Recruitment for this service works as follows. Translators are native in the target language and screened on domain samples.
- MT training
- Multilingual LLM eval
- Product localisation data
Timelines
2-4 weeks for typical corpus volumes per language pair.
Multi-language programmes run in parallel rather than in sequence, so a five-language scope does not take five times as long.
