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