Creating Audio Clips

[Joe Lewis Wilkins]

Hi Everyone,

I've a program in which, rather than have the computer voices reading  
some text, I'd like to have real voices called that would speak the  
text. Presumably, I need to provide audio clips that I can call to do  
this. Any idea how to create them?

I have an old application called SoundEdit that I believe will do the  
job, but it is probably not OSX compatible and I'd have to resurrect  
one of my older Macs to use it. Any Rev compatible tool I can use on  
OSX to do the same thing?

TIA,

Joe Wilkins
