phoonnx_pt-PT_dii_tugaphone

This is a text-to-speech voice model for European Portuguese. The voice is Dii, a female voice. It uses the phoonnx VITS architecture with the tugaphone Portuguese phonemizer, exported to ONNX for CPU inference. It was fine-tuned from the base voice pipertts_pt-PT_dii, the closest available language for this voice.

Model details

Field	Value
Repository	Phoonnx/phoonnx_pt-PT_dii_tugaphone
Voice id	OpenVoiceOS/phoonnx_pt-PT_dii_tugaphone
Languages	pt-PT
Architecture	VITS
Text input	tugaphone phonemes, IPA alphabet
Punctuation	Not recorded in the config. phoonnx removes punctuation before synthesis. The training code passed the punctuation tokens of tugaphone 0.0.x to the model.
Sample rate	22050 Hz
Speakers	1
Training code	phoonnx, version stamp 0.2.7a1 (the version string of the training code; a development build carries the stamp of an earlier release)
Phonemizer	tugaphone, version not recorded. If a released tugaphone was used, it was at most 0.0.2 (released 2025-10-12), the newest release before the model was first uploaded on 2025-10-13.
Training data	Phoonnx/tts-train-synthetic-dii_pt-PT_v2
Base model	Phoonnx/pipertts_pt-PT_dii
Training checkpoint	epoch=655-step=89216.ckpt, in this repository for fine-tuning
Trained by	TigreGotico Lda
Licence	CC BY-NC-ND 4.0

How to use

Install phoonnx:

pip install --pre phoonnx "scriptconv[pt-phonemizers]"

Then run:

import wave
from phoonnx.model_manager import TTSModelManager

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

voice = manager.voices["OpenVoiceOS/phoonnx_pt-PT_dii_tugaphone"].load()

with wave.open("output.wav", "wb") as wav_file:
    voice.synthesize_wav("Bom dia, como está?", wav_file)

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

{
  "tts": {
    "module": "ovos-tts-plugin-phoonnx",
    "ovos-tts-plugin-phoonnx": {
      "voice": "OpenVoiceOS/phoonnx_pt-PT_dii_tugaphone"
    }
  }
}
