great, however...
i just wanted to clarify some stuff to totally get this down perfectly...
first of all, it's spelled PHONEME, and while it does apply to the shape a person's mouth makes when they say a sound, specifically it's the smallest discernable phonetic unit. For example, in the words CAT and MAT, the phonemes "C" and "M" distinguish the two words. So it's not really the shape of the mouth, but the sound itself.
