Additional voices for text to speech?

I'm looking for additional voices for the Text to Speech engine and how to install them. I tried searching but I was unable to find anything that would apply to Windows 7.

To clarify, you go into control panel, Speech Recognition, and then open the Text to Speech menu. Under Voice Selection there's a dropdown menu with only one option, Microsoft Anna. XP had Microsoft Sam (who I liked better) and was able to load in third party voices. But I cannot figure out how to download or install any other voices into Windows 7. Has anyone done this before and able to help?

Edit for clarification: My reason for this is for use with the Ventrilo chat client, which uses the Windows TTS engine so it can only use voices that are installed on the computer. I don't much care for the default Microsoft Anna, and more choices are always better, so I'm looking how to install additional voices, especially Microsoft Sam.

hmmm i've never looked at this, i'll check on that and post any findings here

from what i read these are compatible with windows 7 tts Free Text To Speech (TTS) - YAKiToMe!
