“Talk to you Apple device” by Todd Derek
Todd covered Top 10 Ways to Interact with Siri, dictating to your iOS device and your Mac, and a preview of the new iOS8 (coming in fall) feature of adding your voice to text.
Todd also introduced a great website, http://www.siriuserguide.com, which covers a lot of great information about how to use Siri, and commands to use for Siri and dictation.
