ASR Model Training Data for AI Companies
Product and platform teams that need Indian-language training data on a schedule that matches their model release cycle, not a vendor's studio availability. Building or fine-tuning speech recognition for Indian languages from scratch or from a multilingual base model.

Where the two meet
Model accuracy collapses on Indian accents and languages that were absent from the pretraining mix That is a asr model training problem, and it is solved by data shaped like this:
- Hundreds to thousands of hours of verbatim-transcribed speech
- Wide speaker diversity: age, gender, region, education, recording condition
- Speaker-disjoint train/dev/test splits
Your evaluation criteria
- Can the partner field the speaker count and demographic quotas exactly as written?
- Is consent documented per speaker and mapped to file IDs?
- Are QA thresholds measurable and reported, or asserted?
- Can delivery be staged so training can start before the full corpus lands?
Metrics
- Word error rate overall and per dialect
- Entity error rate on names and numbers
- Code-switch token accuracy
Pitfalls
- Read-speech-only corpora that do not transfer to spontaneous audio
- Speaker leakage across splits inflating reported accuracy
- Normalised-only transcripts with the raw text discarded
Contract points
- Perpetual, transferable licence to the delivered data
- Clear IP assignment
- Consent that survives model distribution
- Data residency and handling
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.
