Knud Haugaard Sørensen suggested this one.  From his email on the
Aspell mailing list:
   
consider these examples:
     a fone number.
      -> a phone number.
     
     a fone dress.
      -> a fine dress.
   
the example illustrates that the right correction might depend on the
context of the word.
   
So I suggested that you take a look on HMM to solve this problem.
   
This might also provide a good base to include grammar correction in
Aspell.

I think it is a great idea. 
 However unfortunately it will probably be very complicated to implement. 
 Perhaps in the far future.
