[Aspell-user] Generating Mispellings

[Jon Shoberg]

I'm looking to do the opposite of aspell.  I would like to take a word
and have a program (or write a program) that would generate common
misspellings there of. 

So the word "furniture" would return "furntiure" or "furnituer" 

Is this a capability of aspell? Anyone know of a program to do this?
Some sort of API?

Everyone has a spelling corrector, but nothing to generate them.

Thanks
Jon
