exact.

hm, I'm not sure if I get your problem right here. Let me give an 
example:
If you missspell the work "cought" (from catch), if you write a word 
you mostly know how to pronounce it but you may not know how to write 
it correctly - but no matter how you think it will be written you will 
probably spell it so, that it would be pronounced the same way as 
"cought", for examply you might spell it "cout" or "coud". The main 
point in the phonetic correction method is that all this writings 
result in the same phonetic result, even if the word's spelling is 
very different from the correct one. Because GH in "cought" is almost 
unhearable, the phonetic rules simply cut it out, simplify it away. :)

This ways, the phonetic result of "cought" might be "C*T" and the 
phonetc result of "coud" might also be "C*T", which makes aspell be 
able to bring up a sugegstion for it, simply by finding a word which 
has the same phonetic.

I hope I could help you with this, could I? Should the documentation 
be made better? If you like you can send me corrections or say which 
part is not good to understand.
BTW - are you trying to do an aspell phonetic table for any language?
