I knew that, but that's only because I read the bio of her as well. However, I don't find it all that surprising; voice actors wouldn't make much of a living if they only could do one character or one show. Part of the talent required to become a voice actor is the ability to do a wide range of vocal styles, each one completely different from the next - being recognizable is a sign of a bad actor, being unrecognizable, however, is a sign of a great one (for instance, would you recognize Mark Hamill of Luke Skywalker fame as the voice of the Joker on Batman? I know I didn't).

Many of the voice actors for FFX/X-2 have had lots of other roles, both voice and regular actung. For instance, Wakka is the voice of Bender in Futurama! O'aka's voice actor, Dwight Shultz, played Reg Barclay for years on Star Trek.
