Chatterbox Multilingual: Brazilian Portuguese
Chatterbox Multilingual: Brazilian Portuguese is a dedicated single-language finetune in the Chatterbox Multilingual V3 Single Language Pack. It is optimized for Portuguese as spoken in Brazil, with language- and region-specific behavior for expressive text-to-speech and voice cloning.
Use this model when you want tighter Brazilian Portuguese quality control than the broad multilingual checkpoint. For a single model that covers all supported languages, use ResembleAI/chatterbox.
