Apparently the Trooper mirror class Bounty Hunter has Grey DeLisle doing the female voice. I never play female chars, but that may very well tempt me to create a second BH at some point.
I've playeg a bit of everything pretty much between beta and live, and I have to say the Trooper/BH is a pretty good mix. It's probably the class I'd recommend to people new to MMOs. The BH is especially friendly with a healer as the first companion. Really lets you wade in with abandon.
