Why we record in Delhi

The deepest single-city Hindi pool in India, plus the professional Hinglish register that most enterprise voice products are built against.

Khari Boli Hindi with heavy Punjabi and Haryanvi contact, plus large Bihari and Eastern UP migrant populations. Urdu is available at depth in the old city, which is a distinct recruitment catchment from NCR generally.

Recruitment pool

Largest single-city Hindi pool, plus deep Punjabi and Urdu availability.

Over-represents confident, professionally exposed speakers. Under-represents the rural Hindi belt that a national model needs, despite the surrounding states being exactly that.

City choice is a data-quality decision, not a logistics decision. It determines which dialects end up in your corpus.

06

Running sessions in Delhi

NCR sprawls across three states, so recruitment radius and participant travel reimbursement matter more here than anywhere else. Winter air quality causes genuine session cancellations, and peak summer suppresses afternoon attendance.

07

Field recording conditions here

Traffic-heavy outdoor capture, market interiors and vehicle recordings, with strong seasonal variance in background profile.

08

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.

09

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
