You can try that using the MBrola text to speach system (it allows you to 
adjust speed keeping pitch) - once i testet it with 50..150% - it's really 
getting hard then, think i will have to adjust my positronic subprocessors 
;-))

But i remember of a video recorder which does that trick up to 9times speed by
simply using small audio fragments - it worked even backwards: the sound was 
played forward... is'nt that the way to go ? much simpler...
