Asking Siri a Question
Siri is ready when you are, so long as you have an Internet connection, be it cellular or Wi-Fi. You can activate Siri in one of three ways:
The most common way is simply to press the Home button at the bottom of the iPhone, iPad, or new iPod touch.
Press the main button on your wired or wireless headset, if you wear one.
If you use an iPhone 4s or iPhone 5, you can set up your phone to activate Siri when you lift your device to your ear (Settings→General→Siri→Raise to Speak).
Regardless of how you activate Siri, you’ll hear a brief chime that confirms Siri is listening for your question or command. If you look at your screen, you’ll also see a small purple microphone icon at the bottom of the screen. (The more purple you see on the microphone, the better Siri can hear you. And the quieter the environment, the better.)
When you ask or instruct Siri with something — such as “Where’s Iron Man 3 playing near me?” or “Post to Facebook: Guess what, world? We’re having a baby!” — Siri will process your request by showing you a lighting circling the microphone.
Siri will give you the answer verbally or tell you something like “this might answer your question” and show you the results on the screen.
