Dictation and text-to-speech on iPad

I really am a slow learner! Or, should I say, it takes me ages to get to know the full potential of anything. As you know, I have had my iPad for some time now but have only just discovered the Dictation capability! (See link below for finding it on your iPad) I have had so many laughs trying this out as my accent must be really strange as the text result can be pretty bizarre. But, as they say, “practice makes perfect” and I am not giving up. One of these fine days I will be able to dictate my message via Messenger on FaceBook or even dictate a whole e-mail to a friend instead of slowly typing out each word.

Another great feature is having long texts read to me instead of straining the vision I have. Has anyone else found any good dictation and/or text-to-speech apps for desktop or mobile devices?
