I am looking for some PC software that will display an animated face at the same time as talking using text to speach.

I want to use it for providing information/running presentations as I don't particularly want to record myself!

I know the software exists as I have used a few different versions in the past, but for some reason I can't find anything suitable at the moment.

So I thought I would turn to my friends at AOC, is anyone able to help?
