Could people develop a functional synesthesia?
I have heard of something called synesthesia where people are able to naturally combine senses much as you decribe "hearing the phone ring as green." People born with synesthesia may smell red as coffee or hear the color blue as middle C (for example.)
I am wondering if a person with dylsexia could learn to hear letters and therefore hear spelling so that if they can not see that a word is spelled incorrectly, they may hear that it is spelled incorrectly ... something along these lines??
