Got a friend who has a vision problem, he has a hard time reading text and running progams. What options does he have?

There got to be something to help him out. Im planning to add voice commander to his phone but does anybody got a lead on a text to speech or magnifier program floating around, registry edits would work to, anything to make the text huge. He had surgery done to his eyes, so any help would be great. He has a mogul, I got the big button dialer on there for him, I would like the keyboard to call out the letters as he types texts then read it back to him. There has to be something out there....
