The TTS-STT Flywheel: Synthetic Entity-Dense Audio Closes the Indic ASR Gap Where Commercial and Open-Source Systems Fail

This paper introduces a self-contained TTS-STT flywheel to close the gap in niche-domain Indic ASR where commercial and open-source systems fail. It synthesizes entity-dense audio to significantly improve the Entity-Hit-Rate on challenging datasets for languages like Telugu.
