Where the two meet
Production audio is 8 kHz telephony; models trained on studio audio degrade sharply 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
- Is narrowband simulated at capture, not by downsampling studio audio?
- Are agent and customer on separate channels?
- Are emotion and escalation variants available on demand?

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
- Consented synthetic-scenario audio with no real customer PII
- Scenario library ownership
- Per-scenario volume guarantees
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.
