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 code-switching asr problem, and it is solved by data shaped like this:
- Genuinely code-mixed spontaneous speech
- Per-token language ID labels
- A fixed rule for script of English tokens
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
- Switch-point accuracy
- Mixed-utterance WER
- Language ID token accuracy
Pitfalls
- Concatenating monolingual data and calling it code-mixed
- Leaving script conventions to individual annotators
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.
