Dragon Dictation is a free speech recognition app for the iPhone, iPod touch, and iPad. All you have to do is tap the screen to start a recording and when you’re done talking Dragon will automatically convert your words to text. I found the app was pretty accurate when I tested it with an iPod touch and a headset, but it did make a few errors. Fortunately, Dragon Dictation has some excellent tools that let you make corrections by tapping a word to see a list of similar words or by pulling up an on-screen keyboard.
You can also copy the entire chunk of text to paste it into another app. And Dragon recently launched an updated version of the app which adds support for sharing your text on Twitter or Facebook, making it as easy to post status updates on those networks as it is to talk into your phone’s mic.
Version 2.0 also adds multilingual support, and the ability tp paste text into the iPhone SMS client.
Dragon Dictation 2.0 is available as a free download from the App Store.
