Voice Biometrics Data for Speech AI Companies
Teams whose core product is speech recognition or synthesis, where dataset quality is the product roadmap and word error rate is the metric everyone watches. Speaker verification and anti-spoofing systems that must work across Indian languages and telephony channels.

- Metric
- Equal error rate
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 voice biometrics problem, and it is solved by data shaped like this:
- Many sessions per speaker across days and channels
- Same-speaker channel variation
- Optional spoof and replay sets
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
- Equal error rate
- Cross-channel EER
- Spoof detection rate
Pitfalls
- One session per speaker, which makes intra-speaker variability unmodellable
- No channel variation
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.
