if you want true synthesis rather than samples

tis not great though , allthough getting it to sing nonsense is quite good fun

Is there one that uses samples of all the different syllables? That'd be good...

a few differnt types of voice there, its phonetic so you can sometimes get better results from spelling words how they sound as apposed to how they are in the dictionary
