Recruitment pool
Needed for Gujarati dialect spread beyond Ahmedabad.

City choice is a data-quality decision, not a logistics decision. It determines which dialects end up in your corpus.
Studio setup
Partner booth with trade-domain scenarios.
Running sessions in Surat
Industrial shift patterns dominate scheduling — sessions run around shift changes rather than office hours, which is unusual for the network and needs local coordination.
Field recording conditions here
Factory floors and dense worker housing, providing industrial and crowded-interior noise 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
