Dyslexic/Dysgraphic+ DD10 has been leaning heavily on voice to text for the past couple of years but Dragon had difficulty picking up her voice. (Not designed for use with children's voices plus her speech issues made it even harder.) The built in iPhone and iPad apps worked much better but no where near perfect. Last spring they tested using the built in software on iPad 3 or above and it works like a charm. There is also a feature in CoWriter that allows her to move back and forth between voice-to-text and keyboarding so if there is a word it doesn't understand she can type her attempt or she can have the iPad "speak" her word prediction options. It proved so much better for her that our district agreed to upgrade and purchased her a new machine for this school year (I think it's an iPad Air) and we are considering buying a new one for her to use at home as well.
