Why we record in Indore

Malwi-influenced Hindi from central India, a large speaker population that public corpora treat as indistinguishable from standard Hindi.

Hindi with Malwi substrate, plus a significant trading community with Gujarati and Marwari contact.

Recruitment pool

Good mid-size-city Hindi pool at lower cost than metros.

Central Indian Hindi is systematically under-represented in existing corpora, so this cohort adds variance rather than reinforcing the mean.

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
