Your problem

  • Web-scraped Indian-language text is thin, noisy and heavily transliterated
  • Code-mixed Hinglish is nearly absent from any structured training source
  • Provenance and consent for human-generated data must survive external audit

What Marathi requires

  • Retains the retroflex lateral ळ, which has no Hindi or English equivalent and is frequently substituted with ल by non-native transcribers
  • Dialects: Standard (Puneri), Varhadi (Vidarbha), Marathwadi, Konkani-influenced coastal Marathi
  • Mumbai and Pune speech mixes Marathi, Hindi, and English in the same sentence. Marathi-only recordings collected in Pune under-represent the Mumbai reality of tri-lingual switching.
  • Available Marathi speech data is dominated by standard Puneri read speech. Vidarbha, Marathwada, and coastal Konkan varieties are severely under-collected, which is exactly where deployed voice products lose accuracy.

How you will evaluate the delivery

  • Is every item traceable to a screened, consenting contributor?
  • Can contributors be screened by domain expertise, not just language?
  • Is there an adjudication process for disagreement on subjective tasks?

Example requirement

"We need 2,000 hours of Marathi from 3,000 speakers, 50/50 male-female, ages 18-45, studio quality, scripted plus spontaneous, delivered in WAV with transcripts."

That sentence is enough to produce a quote and a timeline. Anything missing, we will ask about once.
