[P] Added 8 Indian languages to Chatterbox TTS via LoRA — 1.4% of parameters, no phoneme engineering [P]

A community researcher shared on r/MachineLearning how they extended Chatterbox TTS — Resemble AI's open-source, 500M-parameter model — to support 8 Indian languages using LoRA (Low-Rank Adaptation), updating only approximately 1.4% of the model's parameters. The approach required no phoneme engineering, demonstrating that highly parameter-efficient fine-tuning can enable new language support in TTS models without complex linguistic preprocessing pipelines. This builds on Chatterbox's existing architecture, which uses a CosyVoice-style modified Llama backbone and already supports zero-shot voice cloning and emotion exaggeration control.
