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 framework on Luxembourgish speech data from the Lëtzebuerger Online Dictionnaire (LOD) 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.

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)
