Dialect profile
Bhojpuri and Magahi-influenced Hindi, a major deployment market and a major corpus gap.
Recruitment pool
Critical for eastern Hindi-belt coverage.
The single most valuable counterweight to Delhi in any Hindi cohort, and the one most often left out.
City choice is a data-quality decision, not a logistics decision. It determines which dialects end up in your corpus.
Studio setup
Partner booth plus mobile field recording.
Running sessions in Patna
Limited studio infrastructure, usually requiring a mobile rig alongside the fixed room. Recruitment is fast and the pool is entirely unsaturated.
Field recording conditions here
Small-town and rural environments within short reach, with genuinely non-urban acoustic profiles.
The numbers we hold ourselves to
- 100% of delivered files pass automated technical QA for SNR, clipping, duration and silence
- 5-25% of files pass a second native-speaker content review, stratified by city, dialect and transcriber, and escalating to 100% on any batch that fails the agreed threshold
- Accepted yield runs 85-90% for scripted speech, 60-70% for spontaneous, 55-65% for conversational and 50-60% for telephony
- Default cohort quotas: 50/50 gender, with age bands at 30% (18-25), 40% (26-40) and 30% (41-60)
- 48 kHz / 24-bit capture, delivered as 16-bit PCM WAV, with studio sessions held below a -50 dBFS noise floor
- First response within one working day; a scoped, fixed quote within two to three
These are the figures a delivery is measured against, not aspirations. A batch that misses them is re-recorded at our cost rather than repaired.
What every session includes
- Local coordinators recruit and screen against your quota matrix
- Participants are briefed and consented on site
- Sessions run to the same template as every other city in the network
- Technical QA runs on upload, so defects are caught while the speaker can still be recalled
