matcha-cat-multiaccent-wavenext

A Matcha-TTS model by Projecte AINA, from projecte-aina/matxa-tts-cat-multiaccent, packaged for phoonnx, our ONNX text-to-speech library.

Model details

Architecture	Matcha-TTS
Upstream	projecte-aina/matxa-tts-cat-multiaccent
Author	Projecte AINA
Languages	ca
Text input	espeak phonemes, IPA alphabet

How to use

pip install --pre phoonnx

The phonemes come from the espeak-ng program, so install it too (for example apt install espeak-ng). Without it, pip install --pre "phoonnx[espeak]" gives phoonnx the espyak port of espeak-ng. Some espyak phonemes differ from those of espeak-ng, so the voice can say some words wrong with espyak.

import wave
from phoonnx.model_manager import TTSModelManager

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

voice = manager.voices["OpenVoiceOS/matxa-cat-multiaccent-wavenext"].load()

with wave.open("output.wav", "wb") as wav_file:
    text = "..."  # a sentence in ca
    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": "OpenVoiceOS/matxa-cat-multiaccent-wavenext"}}}

Text front end

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

• espeak: EspeakPhonemizer from scriptconv.phonemizers.mul, installed by the scriptconv[espeak] extra.

phoonnx voices

• OpenVoiceOS/matxa-cat-multiaccent-wavenext
