GPT-SoVITS is a powerful few-shot voice conversion and text-to-speech system by [RVC-Boss](https://github.com/RVC-Boss).
It achieves high-quality voice cloning with just 1 minute of training data, supporting zero-shot and few-shot TTS
with cross-lingual synthesis capabilities.

```

## Usage

```python
from ttsdb_gpt_sovits import GPTSoVITS

# Load the model (downloads weights automatically)
model = GPTSoVITS(model_id="ttsds/gpt-sovits")

# Synthesize speech
audio, sample_rate = model.synthesize(
    text="Hello, this is a test of GPT-SoVITS.",
    reference_audio="path/to/reference.wav",
    text_reference="Transcript of the reference audio.",
    language="eng",
)

# Save the output
model.save_audio(audio, sample_rate, "output.wav")
```
