New to synthv and need help

[Aika]

Anyone know how to make singers sing something like only the "s, t, ch" etc
I wanna make renri sing in "s" words but it sounds weird

You might want to use another voicebank for them to make "s" sounds.
Yamine renri has a weird thing where at the end of a word with s in it, she says "eee" and I don't know why.
I recommend using an AI voicebank such as Tsunia-Chan AI or Hanakuma Chiyufu AI.
Then add a note, change the phonemes to whatever word you're trying to put in "Engrish" (Or just the s sound / word you were talking about), then test it out.
Idk if this helps but i'm just trynna help you since I have more experience in Synthesizer V.
