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). ## Demo Try the hosted demo Space: [`ResembleAI/Chatterbox-Multilingual-TTS-pt-pt`](https://huggingface.co/spaces/ResembleAI/Chatterbox-Multilingual-TTS-pt-pt). ## Files - `t3_pt_pt.safetensors`: T3 state dict in safetensors format. - `s3gen_v3.pt` / `s3gen_v3.safetensors`: V3 S3Gen speech decoder checkpoint. - `grapheme_mtl_merged_expanded_v1.json`: multilingual tokenizer config. ## Language - Locale: `pt-PT` - Chatterbox language ID: `pt` ## Checkpoint Metadata - Source step: `137700` - Source checkpoint: `t3_137700.pth.tar` - Tensor count: `292` - Dtype: `float32` - Text embedding shape: `(2454, 1024)` - Speech embedding shape: `(8194, 1024)` - Size: `2143990296` bytes - SHA256: `547c6e734908621badc806f5b56d773f05271b4ae653ae448c5d068e94de12db` ## Loader Notes This repository contains Chatterbox Multilingual V3 single-language assets used by the linked demo Space.
