Brais: Nós Project's Galician TTS Model
Model description
Brais is a Galician TTS model developed by the Nós project. It was trained from scratch using the Matcha-TTS Python library on the corpus Nos_Brais-GL. This corpus comprises a total of 16,121 sentences recorded by a professional male voice talent, corresponding to approximately 18 hours of speech.
The model was trained directly on grapheme inputs, so no phonetic transcription is required. The Cotovía tool can be used to normalize the input text.
Intended uses and limitations
You can use this model to generate synthetic speech in Galician.
Installation
Cotovía
For text normalization, you can use the front-end of Cotovía. This software is available for download on the SourceForge website. The required Debian packages are cotovia_0.5_amd64.deb and cotovia-lang-gl_0.5_all.deb, which can be installed using the following commands:
To synthesize speech, you need to install the Coqui TTS library:
pip install matcha-tts
How to use
Command-line usage
The following command normalizes and synthesizes the input text using the Brais model:
matcha-tts --text "a erupción provoca a emanación de gases á atmosfera." --checkpoint_path brais.ckpt --vocoder hifigan_univ_v1 --output_folder . --speaking_rate 1
The output synthesized speech is saved to the specified audio file.
This research was produced within the framework of the Proxecto Nós, funded by the Ministry for Digital Transformation and Public Administration and the Recovery, Transformation, and Resilience Plan – Funded by the European Union – NextGenerationEU, as part of the Ilenia Project with reference 2022/TL22/00215336, and previously “The Nós project: Galician in the society and economy of Artificial Intelligence”, resulting from the agreement 2021-CP080 between the Xunta de Galicia and the University of Santiago de Compostela, and thanks to the Investigo program, within the National Recovery, Transformation and Resilience Plan, within the framework of the European Recovery Fund (NextGenerationEU).
