-Korean voicebank, and maybe a French one?
-Glottal stop across all languages. English has a hidden one (q) but it isn’t pronounced super well
-AiKO AI. I can’t emphasize this enough aaaaa
-vocal fry feature
-a feature to add more emotions? A voicebank doesn’t usually sound inherently sad or angry, and it’d be really cool to hear that.
-A list of pitch edits you can make to make the voicebank sound more realistic (for non-AI voicebanks and/or to strengthen current AI voicebanks)
Keep in mind these are things I think would be cool and they’re nothing more than that.
