Where the two meet
WER on Indian languages is dominated by dialect and code-mixing failures that generic corpora do not cover That is a accent adaptation problem, and it is solved by data shaped like this:
- Accent-band balanced speech with substrate-language tags
- Matched content across bands for controlled comparison
Your evaluation criteria
- Are train/dev/test splits speaker-disjoint by construction?
- Is transcription verbatim, with disfluencies preserved?
- Is per-token language ID available for code-mixed speech?
- Is inter-annotator agreement measured and reported?

Metrics
- Per-accent WER spread
- Regression on the original accent set
Pitfalls
- Treating Indian English as one accent
- No substrate tagging, so the model cannot be evaluated per band
Contract points
- Speaker-disjoint splits guaranteed contractually
- Right to publish benchmark results
- Re-record remedy for QA failures
Frequently asked
What does a first engagement look like?
Usually a scoped pilot: one language, an evaluation set plus a first training batch, delivered in three to five weeks, followed by the full programme.
Can you match our existing vendor's schema?
Yes. Working to your schema avoids a conversion pass and keeps deliveries comparable across vendors.
How is provenance documented?
Per-item contributor records and consent mapped to IDs in the manifest.
