This...is actually highly remarkable. That this sounds just like a "bad" vocal performance and not a completely stitched together voice in of itself is amazing. I'm pretty sure given time and refinement, this would sound more like her.
I like the fact that the pitch is lower than what Tracey typically used for Sailor Moon.
It's really sad, though, that a lot of VA's are speaking out against this technology. While I can understand the worry about impersonation, the reality is this only works if one has access to a large voice bank, and I'm pretty sure the real actor would still be more convincing.
Can you imagine if AI got to the point where it could reliably voice fanfics?
