I saw this many years ago as a pen. I have a daughter who is 30 years old she is mildly mentally impaired. The most difficult challenge for her is reading. She struggles to this day sometimes putting in sounds not in the word. She has taken literacy classes at the college ever since she graduated high school.There is noone that tries as hard as she does, it breaks my heart. If they could get this technology to speak a little better she would have more educational opportunities available to her.
