Thanks to this neat program I found all you have to do is type, listen, save, and compress to get voice in your map!
Presenting Speakonia
This program has a complete guide included in the download, If you register (which is free) you can save the file as a .Wav and compress in any sound compresser and put it in your map.

old. ;o I first downloaded it at the old SEN.

Haha, This program is so funny!
I'm sure this will be helpful to me. Thanks!

or if you want you can go the expensive route with FL studio and its voice synthesizer.. or that cool realisticish sounding thing off the internets. called sitepal i think. but for if you want odd sounding, computer voices, or robots go for fl studio, also you could do some sexy editting in like soundforge. but ya sitepal is hilarious..
