I have no idea. I don't want to download a whole Voice Bank to find out D; Dude.
Any videos or listen-on-site demos?
Blue bar/Front cut off zone- Cuts off silence and slurs on soft consonants (s, l, f, h, n, m etc), when beta-ing otos, best to just put it at the start of the sound.
Red line/pre-utterance- Goes at the start of the vowel/end of the consonant. That's all you really need to know. Mess with it later while on a UST with the Overlap and Preutterance cleared to see what it actually does XD
Green line/Overlap- Goes halfway in between the red line and the front cut off zone.
Pink bar/how much of the sounds is stretched- Goes over the start of the vowel for a little bit.
Back cut off zone- Cuts off the natural fade off at the end (so it flows better into other vowels).
