🎙️ Live demo: Try this model in the ResembleAI/Chatterbox-Multilingual-TTS-hi Space.

Chatterbox Multilingual: Hindi

Chatterbox Multilingual: Hindi is a dedicated single-language finetune in the Chatterbox Multilingual V3 Single Language Pack. It is optimized for Hindi, with language- and region-specific behavior for expressive text-to-speech and voice cloning.

Use this model when you want tighter Hindi quality control than the broad multilingual checkpoint. For a single model that covers all supported languages, use ResembleAI/chatterbox.
