Sabela: Nos Project's Galician TTS Model
Model description
This model was trained from scratch using the Coqui TTS Python library on the Sabela corpus of the dataset CRPIH_UVigo-GL-Voices.
A live inference demo can be found in our official page, here.
The model needs the Cotovia tool to work correctly. For installation and deployment please consult the Cotovía Preprocessor section.
Intended uses and limitations
You can use this model to generate synthetic speech in Galician.
How to use
Usage
Cotovía preprocessor
To generate fonectic transcriptions, the Cotovía tool is needed. The tool can be downloaded from the SourceForge website. The required debian packages are cotovia_0.5_amd64.deb and cotovia-lang-gl_0.5_all.deb, that can be installed with the following commands:
sudo dpkg -i cotovia_0.5_amd64.deb
sudo dpkg -i cotovia-lang-gl_0.5_all.deb
The tool can be used to generate the phonetic transcription of the text. The following command can be used to generate the phonetic transcription of a text string:
echo "Era unha avioneta... O piloto era pequeno, que se chega a ser dos grande, tómbate!" | cotovia -t -n -S | iconv -f iso88591 -t utf8
The output of the command is the phonetic transcription of the input text. This string may be used in the inference part, as shown next.
Required libraries:
pip install TTS
Synthesize a speech using python:
import tempfile
import numpy as np
import os
import json
from typing import Optional
from TTS.config import load_config
from TTS.utils.manage import ModelManager
from TTS.utils.synthesizer import Synthesizer
model_path = # Absolute path to the model checkpoint.pth
config_path = # Absolute path to the model config.json
text = "Text to synthetize"
synthesizer = Synthesizer(
model_path, config_path, None, None, None, None,
)
wavs = synthesizer.tts(text)
