this is a python script I made mostly for stream. I wanted to have an easier way to use the phoneme support that dectalk has.
python 3.12
pip install pykakasi
python conv.py <song.ustx>
Dectalk only supports one singer at a time, so please match that in OpenUtau. Also I haven't tried what would happen if I had multiple singers, so there's that.
If your song is over 120 bpm it won't work right, notes will be held down for to long. To fix this you can go to Project => Adjust Tempo (Preserve Timings)
