Any New Voices for Text to speech?

I have been waiting a while to test the new text to speech, and speach
recognition of Vista. I have found it a major leap from what was avallible.
The default voice for the system and the only voice that loads it a female
voice. it is a great voice and reads very well, but i was wondering if there
was any male voices availible or could I get info for compatible voices to
load on the system without having to load another voice engine as well.

and info is appreciated.
