As far as I know, EmpathP is british. Correct me if I'm wrong, but I doubt she's the voice provider in general cuz Aki has a sweeter tone, unlike Daina who has that particular raspiness.

Her high notes are still a problem (like, with most Vocaloids) since they are too squeaky and have several warp noise, specially on [i:] phoneme. Dunno if they'll fix it but I bet that if you put Cyber Diva, Daina and Ruby singing along in high notes you will barely notice differences between them, being Cyber Diva's clearness the only notorious thing.

Perhaps is, as I said, because of the particular american accent. Dunno. But she do sounds like a mature female voice trying to sound youngish.
