f you find yourself fumbling with your iPhone to make a simple phone call, locate and launch an app, set a reminder or wake-up alarm then you’re probably not using Siri enough. If you still don’t know about Siri or you’re new to the iPhone or iPad, Siri allows you to issue voice commands on your device, saving you the trouble of all the tapping, typing, and searching by hand.

Siri was first introduced with iOS 5, back in 2010. We have covered what you can do with Siri, from calling people and making restaurant reservations dictating messages and notes using the voice to text feature. In this article I highlight some of the new commands in the iOS 7 version of Siri, as well as suggest some tips for getting the most out of the feature
Your First Siri Command

Your first Siri command couldn’t be easier. Whether your iPhone or iPad is in lock mode or not, simply press down on the Home button until you here the two-tone prompt and the new Siri screen comes up. If you don’t know what to say, you can tap on question at bottom-left of the screen to get a list of commands, or if you don’t speak for a few seconds a list of commands will appear on the screen.

The list of Siri commands you see are related to all of the default iOS apps. Tapping on a listed app gets you additional commands and questions you can use. But if you’re just getting your feet wet with Siri you might feel a little overwhelmed with the long list. I will highlight a few of the new and most practical commands you might should know about.
