This is not a new product but it is certainly one I really recommend if you would like to input text via your voice rather than through typing on a qwerty-keyboard. Really useful for students with dyslexia as I noticed yesterday as two Rödaberg students "wrote" their English assignments through the microphone on their iPads. The app is totally FREE and very easy to use. The text that appears can be sent by e-mail to your inbox or saved on the iPad/iPhone.
You can find it at the AppStore or in iTunes.
