Hi, I was just curious to know where I can find any free or at least reasonable priced addon voices for use with vox atc. I have searched the internet several times and the only thing I could find was AT&T real voices but that is way out of my price range. All help is appreicated because right now all I have are the default MS voices, Mike, Mary, and Sam.

This site has many voices for sale but still may be too expensive. I believe the least expensive was $29.95 per voice.http://www.nextup.com/index.html

There are a number of options out there. Search for SAPI5 compliant voices. As mentioned here nextup.com is a goodplace to start. Typically you purchase the enhanced TTS, text to speech, engine which generally includes both a female and male voice. This package is typically priced from $35 USD and up. Additional voices are typically around $30 USD each. Unfortuately these inhanced voices don't come cheap. Good luck.
