Chatterbox adds 8 Indian languages via LoRA
Chatterbox-Indic-LoRA is an open-source extension of Resemble AI’s Chatterbox-Multilingual that adds support for 8 Indian languages via LoRA fine-tuning. By leveraging script-aware embedding initialization and tokenizer extensions, the project bypasses complex phoneme engineering to achieve intelligible speech synthesis for languages like Telugu, Tamil, and Bengali with minimal compute.
Efficient fine-tuning solves the multilingual "representation gap" without full retraining by using rank-32 LoRA adapters and a "Brahmic warm-start" for character embeddings. While this improves performance across Dravidian and Indo-Aryan languages, conjunct-heavy scripts like Malayalam still present significant complexity.
