About
🎙️ Live demo: Try this model in the
ResembleAI/Chatterbox-Multilingual-TTS-zh-cmnSpace.
Chatterbox Multilingual: Mandarin Chinese is a dedicated single-language finetune in the Chatterbox Multilingual V3 Single Language Pack. It is optimized for Chinese Mandarin, with language- and region-specific behavior for expressive text-to-speech and voice cloning.
Use this model when you want tighter Mandarin Chinese quality control than the broad multilingual checkpoint. For a single model that covers all supported languages, use ResembleAI/chatterbox.
