I’ve been testing the Dragon dictation App on the iPad and iPhone. Here’s the test passage with the corrections/omissions encased in square brackets.
Dear I [iPad] this is a most interesting development, and one that I hope we will be able to build on. If I can master [it] adequately I think it would make me more efficient. [On] The other hand, it might seem very strange to others to watch somebody talking to the screen. But if the fish is the games [efficiency gains] were worthwhile then I think I would be able to overcome my embarrassment.
I really like the way it interpreted “efficiency gains” and “fish is the games”! But for short passages (e.g. SMS) it’s often accurate enough — especially given the way iPhone/iPad autocorrect creatively garbles what I type.
