Model Card
Does explicit Devanagari grapheme-to-phoneme conversion still matter for neural text-to-speech, or do modern architectures absorb Hindi schwa deletion from data alone, and does the answer depend on the architecture and on how much data you have? Hindi is the testbed. Marathi is the control: same script, same converter, same phone inventory, no medial schwa deletion. A data ladder from 10 hours down to 10 minutes varies resource level while holding speaker, domain and recording chain fixed. M.Tech dissertation work, NSUT New Delhi. Plan documents live in the attached Claude project. Phases 0 to 2 complete. Both corpora are standardised, the splits are frozen and checksummed, and the ladder…
