Low-resource speech corpus collection (100 hours, 90 days)
A field-collection program for three low-resource Indic languages with no existing corpus — consented, transcribed and WER-checked in 90 days.
By Cognegica Linguistics Team · Linguistics & low-resource language research
100 hrs delivered · WER 6.2%
Languages: Bodo, Santali, Maithili
Illustrative scenario. This case study describes a representative methodology rather than a specific client engagement.
Challenge
The team wanted to extend ASR and speech models to Bodo, Santali and Maithili — languages with effectively no usable open speech data. Scraping wasn't an option, and generic vendors couldn't economically staff native-speaker collection in those regions.
Approach
We ran a documented field-collection operation:
- Recruited and trained native-speaker field crews in each language region, with written, commercial-reuse consent on every record.
- Captured read and spontaneous speech across age, gender and dialect strata to a defined sampling matrix.
- Transcribed and ran speech QA with word-error-rate checks on sampled batches, delivering versioned drops with a data card.
Outcome
100 hours of consented, transcribed speech across the three languages delivered in 90 days, with transcription QA holding word error rate at 6.2% and full provenance and consent references per record — a replicable playbook for the next low-resource language.
