Translation & Localisation Data for Accent Adaptation
Human translation and parallel-corpus creation across Indian languages, built for machine-translation training and multilingual LLM evaluation rather than for publication. Applied to accent adaptation, the specification is driven by one thing: per-accent wer spread.

- Use case
- Accent Adaptation
- Primary metric
- Per-accent WER spread
Required data profile
- Accent-band balanced speech with substrate-language tags
- Matched content across bands for controlled comparison
Technical specification
| Parameter | Standard |
|---|---|
| Direction | English to Indian languages and between Indian languages |
| Output | Sentence-aligned parallel corpora |
| Register | Formal, colloquial, or matched to your product tone |
| Review | Independent bilingual review pass |
| Terminology | Client glossary enforced and returned updated |
Process
- Glossary and register agreement
- Translation by native speakers of the target language
- Independent bilingual review
- Alignment verification
- Delivery with terminology report
Metrics this feeds
- Per-accent WER spread
- Regression on the original accent set
Failure modes to design out
- Treating Indian English as one accent
- No substrate tagging, so the model cannot be evaluated per band
Back-translation checks are run on a sample so you can see where source ambiguity, not translator error, causes divergence.
Deliverables
- Sentence-aligned parallel data
- Updated glossary
- Reviewer notes on ambiguous source
Frequently asked
Is translation the right service for accent adaptation?
It covers accent-band balanced speech with substrate-language tags. Most accent adaptation programmes combine it with at least one other service; we will say so in the scope rather than selling one line item.
What languages are available?
All 14 languages in the network plus Indian English accent bands.
How is the evaluation set handled?
Collected first, from speakers disjoint from the training cohort, so improvement is measurable.
