I'm currently using Microsoft Windows XP which comes bundled with the Microsoft Sam Voice. I want to add more voices as Sam is not very good to work with. Many dictionary software's that i use take the default Microsoft voice for pronouncing and demonstrating new words and sentences. Are there any voices (ideally free, but no limitations can be paid too) available that will add-on directly to the default windows text to speech engine? Can I set one of those voices as a default instead of Sam?

I was going to redo this all TTS Voices series with my Windows 8.1 host, however, every SAPI 5 voice appears to not be working for some reason. I think what happened is I had decided to install.

I don't need a text to speech reader software so i need only the voices, not bundled with any software. Also please suggest voices which are natural. Pdf the game of life fame edition instructions for 1040ez instructions.
