As you can imagine there's no perfect answer here, since words can be typed
piecemeal, or backwards, or split into two, or joined, or modified in some
other way.  So it's not even clear what you mean by "everytime a new word
has been typed".

Take a look at how flyspell does it.  Or maybe auto-fill.

As you probably know, the answer to both is "no can do".
But if you provide more info about what you're trying to do (rather than
how you're trying to do it), maybe there's a good answer that does not
involve the usual "patches welcome".
