# Coqui TTS - Max (Luxembourgish Male Voice)

A VITS-based text-to-speech model for Luxembourgish, featuring a natural male voice.

## Model Description

This model was trained using the [Coqui TTS](https://github.com/coqui-ai/TTS) framework on Luxembourgish speech data from the [Lëtzebuerger Online Dictionnaire (LOD)](https://lod.lu) example sentences.

"Max" is a male Luxembourgish voice based on recordings from a real speaker.

### Model Details

- **Architecture:** VITS
- **Language:** Luxembourgish (lb)
- **Speaker:** Single speaker (male)
- **Sample Rate:** 22050 Hz
- **Checkpoint:** 50,000 steps
- **License:** CC BY-NC 4.0 (Non-commercial use only)

## License Notice

**This model is for non-commercial use only.** All commercial uses are prohibited. The voice data is derived from recordings of a real speaker and may only be used freely for non-commercial purposes.

## Usage

**Note:** Text should be lowercased before synthesis. Additional text normalization may be required.

```python
import torch
import scipy.io.wavfile as wavfile
from TTS.utils.synthesizer import Synthesizer

# Load the model
synthesizer = Synthesizer(
    tts_checkpoint="path/to/coqui-tts-max.pth",
    tts_config_path="path/to/config.json",
    use_cuda=torch.cuda.is_available()
)

# Generate speech
wav = synthesizer.tts("moien, wéi geet et dir?")

# Save to file
wavfile.write("output.wav", 22050, wav)
```
