Vernacular speech-to-text for rural ASHA workers
Problem
ASHA workers record patient interactions in code-switched Hindi and English. Off-the-shelf Whisper-class models hallucinate medical entities and miss Indic phonology, making the transcripts unreliable for clinical follow-up.
Target outcome
A domain-adapted Whisper-derivative reaching >90% medical-term accuracy on a held-out 1,200-utterance evaluation set, with a privacy-by-design audit. Deployed at three primary health centres for a four-week field pilot.
