need to generate a computerized message
 

Is there a website where I can enter some text and it will speak it out in an actual voice?

I want to setup a phone greeting message.

looked on google but not sure how to even search for this. I came across some sites before, where you type some text and it says it out loud but I can't seem to find it anymore.

Are you a mute?

search google for "text to speech" - there are tons and tons of programs that do this.

use this its the best
