Text To Speech

Do you know about any text-to-speech demo that would allow to create *.wav files...?

What i really need is to produce a *.wav file based on an optional text...

Please help!!!

Here is a sample, it is a console application, U type the text u want to store, it saves the text as speech and then plays it, it requires Speech sdk 5 and it creates a wave file with name "test".

Aamir!
