# phoonnx-chatterbox-multilingual

Mirror of the multilingual variant of [Chatterbox](https://github.com/resemble-ai/chatterbox)
by Resemble AI, exported to ONNX for
[phoonnx](https://github.com/TigreGotico/phoonnx), OpenVoiceOS's offline TTS
library, covering 30 languages from Arabic to Vietnamese. Like the base
model, this is an autoregressive codec-LM (Llama backbone) with zero-shot
cloning from an untranscribed reference clip and an `exaggeration` control.
See
[docs/training/engines/chatterbox.md](https://github.com/TigreGotico/phoonnx/blob/dev/docs/training/engines/chatterbox.md)
and [docs/cloning.md](https://github.com/TigreGotico/phoonnx/blob/dev/docs/cloning.md).

The multilingual variant uses its own `ChatterboxMTLTokenizer`. Japanese and
Chinese script normalization need
`pip install phoonnx[chatterbox-multilingual]` (pulls in `pykakasi` and
`spacy-pkuseg`); Korean normalization is pure-Python and always available;
Hebrew and Russian degrade gracefully when their optional
stressors/diacritizers are absent.

(base English), [phoonnx-chatterbox-turbo](https://huggingface.co/OpenVoiceOS/phoonnx-chatterbox-turbo)
(faster GPT-2-based variant), [phoonnx-chatterbox-lahgtna](https://huggingface.co/OpenVoiceOS/phoonnx-chatterbox-lahgtna)
(Arabic dialects, fine-tuned from this model).

## Usage

Cloning support requires `pip install phoonnx[cloning]`.

```python
import wave
from phoonnx.model_manager import TTSModelManager

manager = TTSModelManager()
manager.load()
manager.merge_default_voices()

voice = manager.voices["chatterbox/multilingual/pt"].load()
with wave.open("out.wav", "wb") as wav_file:
    voice.synthesize_wav(
        "Olá, isto é um teste.",
        wav_file,
        speaker_reference="reference.wav",  # optional: clone this speaker
    )
```
