I downloaded the Dragon Naturally Speaking iPhone app for free the other day.
It is a speech recognition software that allows you to dictate 20-30 seconds of speech into your iPhone and then automatically converts your recorded message to text. Then, you can email it, text it, etc.
I’m going to be using it to write sermons without typing when I’m away from my computer. Even though the info chucks are only a paragraph long, it will still be a huge help in sermon prep.
