Despite my grumbles about V2 and Solaria II elsewhere on the forum, I have to say that Liam sounds like it could be a useful addition, and NYL II on first hearing is much improved over the original version.
Have you figured out a way to remove the southern twang? Words like “pass” with the ae phoneme and other vowel sounds that he draws out. Maybe I have to use the new phonetic parameter view and edit these words again, but just putting him on existing vocal tracks reveals his normal twang.
