techiaith-g2p
The permissive Bangor Welsh grapheme-to-phoneme (G2P) engine: turns Welsh (and code-switched English) text into the phoneme-id sequence consumed by Bangor University's retrained Piper/VITS voices. Dictionary-based, permissively licensed data only, and dependency-free -- it imports nothing beyond the Python standard library, so it drops into an inference server, a screen-reader add-on, or a CLI without pulling in a model runtime.
Install
pip install techiaith-g2p
Use
from techiaith.g2p import BangorG2P
g2p = BangorG2P(english_mode="native")
ids = g2p.text_to_ids("Bore da. Sut wyt ti'n teimlo heddiw?")
print(ids)
english_mode and the package's data_version() must match the target
voice's .onnx.json. For the full text-to-audio example, see the model card:
https://huggingface.co/techiaith/cy_en_GB-bu_tts
Do not feed this voice to stock piper. Its phoneme_type: "text" path
treats phonemes as individual codepoints, one at a time -- it does not
understand the multi-codepoint phoneme ids this G2P produces, and the output
will be mispronounced. Use the ids from text_to_ids directly against the
model's input layer, as the model card describes.
