Evernote, one of my favorite and most useful apps, has an update for Evernote's Android app that now includes Speech-to-text. The speech recognition allows you speak and the app will create text into the note. This is also a great way to have transcribed notes without the transcriptionist.
This can also be useful for students and teachers as a learning tool, note taking, and even for students with disabilities to be able to take notes by voice instead of by hand.
The Evernote blogs says it only works on Android 4.0 (ICS) and some other devices, but it works great on my Droid Incredible 2 running Android 2.3.4. I dictated a few notes and it only had one error out of a full paragraph (it missed one letter).
You can get the updated app in Google Play
