Recruitment pool
The only practical base for Assamese collection at scale.
Urban Guwahati Assamese under-represents Upper Assam varieties, which differ substantially.
City choice is a data-quality decision, not a logistics decision. It determines which dialects end up in your corpus.
Studio setup
Booth plus partner field teams across Assam.
Running sessions in Guwahati
The most logistically demanding city in the network: limited studio infrastructure, longer travel and genuine seasonal disruption from flooding. Schedules need real contingency, not nominal contingency.
Field recording conditions here
Riverine and semi-rural environments within short reach, giving genuine access to 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
