And of course FREEDOM!

To get back to the original question, there seems to be two parts to the 
solution.

The first and easiest is to take your speech and change it so that it 
sounds as though it has come from Bush's vocal tract.  For example, DSP 
can be used to equalise the effect of existing vocal tract resonances 
and to insert new resonances.  If this processing is done well, the new 
voice signal might pass a voice-print test but it would not yet fool 
anyone into thinking it was coming from George W. himself.

The second and hardest part is to identify and reproduce the words, 
accent and mannerisms that make W's speech so recognisable.  This really 
needs a skilled mimic.  Interestingly, people who can do this well are 
judged to sound very much like their subject even though their vocal 
tract may not be at all similar.

I don't know how you would even start to tackle this mimicking process 
electronically, however my humble suggestion for doing it 
non-electronically is this:

1.  Practice the accent, and when you have it down really well, start on 
the mannerisms.

2.  Write out some text that is full of crap, as has been suggested, but 
take care to choose your words from the same limited vocabulary as 
George W.

2.  Display the text on a teleprompter. If you don't have a 
teleprompter, print it out in a really large font.

3.  Read the text out as though you are seeing it for the first time, 
raising your inflection as you approach the end of each line regardless 
of the sentence structure.

4.  Look up from time to time to see if everyone is a puzzled as you.

5.  Be sure to say 'freedom' a lot.

Regards,

John

To make a George Bush system just use a system that generates random amounts
of crap with key words 'Iraq',WMDs etc.

I must add do not forget to come up with some stupid sentences if you 
decided to chose Bush, since I assume that you are smarter than him.

It would be quite a challenge to emulate the characteristic slurred 
speech of the (reformed ?) alcohol and cocaine abuser.

I would think that preceding this with a random text generator would
produce a convincing result.

In principle, it shoule be possible. There are text-to-speech engines
that have voice "personalities" built in. The resulting voice sounds
like a person. I suppose you could build a George Bush personality or
whatever. Then, you could have a good speech recognition engine that
converts your speech to text and run it through the TTS.

That said, think of the speech recognition engine and the TTS engine in
terms of reciprocal hierarchical blocks and you could find an
intermediate point to connect the two. Your speech can be characterized
in terms of some parameters which are then passed through a Bush
transform and played out as the modified speech. I know of no
literature that deals with this problem though.
