gentleman101 · Bhojpuri Voice Cloning

Bhojpuri F5-TTS

A rank-32 LoRA (10.1M of 347M parameters trainable) on AI4Bharat's IndicF5, trained on 9.4 hours of IISc's SYSPIN Bhojpuri corpus from two studio speakers, for zero-shot voice cloning from a 3 to 10 second reference clip. On a 32-sentence test set built around Bhojpuri-versus-Hindi pronunciation, pitch-contour correlation rose from 0.502 to 0.601 and pitch error fell from 3.76 to 3.21 semitones, improving all eight categories (self-reported, pitch proxies only, no native-speaker listening test). The author calls it a personal learning project, not production-ready, and asks users not to impersonate the two corpus speakers. Weights CC-BY-4.0, code MIT.
