Hey Siri

On your iOS 8 device, you can have Siri respond to you without even touching your iPhone or iPad. Just turn on Allow Hey Siri in Settings, General, Siri. Then say “Hey Siri” and ask away. This only works when your device is plugged in to power, since it will drain the battery for it to be listening for your voice all the time. But it could come in handy while sitting at your desk or doing work that involves both hands.
