I'm following the NNSVS Voice Database Creation Tutorial linked on the NNSVS carrd. I don't have any experience with AI voices, so I can't say for sure that it hasn't been repurposed for Diffsinger. It definitely seems like it's for NNSVS though.
The phonetic part also showed as [error]. I got the first error message when I tried to play the UST I was using after changing the phonetic part to the right phonemes and the second error message was in the enunu_server.bat file any time I moved a note. What should I do to fix these errors?
can you add a screenshot? afaik renri only has vcv voicebanks so she won't sound right with a cv ust if she sings it at all + if you ARE using a vcv ust, large overlap is normal, you just need to select all the notes and crossfade them with either of the circled buttons
looks like the locale is wrong. make sure you changed the laptop's locale and not just the language + if you set your locale to japanese after installing utau, you'll need to reinstall it
