How to use

pip install --pre phoonnx

import wave
from phoonnx.model_manager import TTSModelManager

manager = TTSModelManager()
manager.load()
manager.merge_default_voices()

voice = manager.voices["coqui/pt-cv-vits"].load()

with wave.open("output.wav", "wb") as wav_file:
    text = "..."  # a sentence in pt
    voice.synthesize_wav(text, wav_file)

In OVOS, phoonnx installs the ovos-tts-plugin-phoonnx plugin. Select the voice in mycroft.conf:

{"tts": {"module": "ovos-tts-plugin-phoonnx", "ovos-tts-plugin-phoonnx": {"voice": "coqui/pt-cv-vits"}}}

Text front end

phoonnx hands the text to scriptconv, our text conversion library, which normalises it and turns it into the model's input:

• graphemes: GraphemePhonemizer from scriptconv.phonemizers.base, in scriptconv itself.
