If you have been using the 4S for a while, and especially if you have been using Siri, you know how to invoke it. When the phone is on standby, just press the home button and hold it. Another way is to invoke it from the “microphone key” on the keyboard just to the left of the space button.
But neither of those is the fastest way to talk to her. Lets say you want to do a quick web search for the nearest post office. If you phone is on, (but not in stand by), no matter what application you are in, (even when you are not running any application – like you are on the launch pad or home screen), just lift the phone to your ear and you will hear the familiar ‘ting-ting’ and you can start speaking. This will work even when the phone is locked. The only requirement is that the screen is on.
If your Siri is not set up correctly here is how to do it.
- Launch the Settings App
- Scroll down to General and tap on it.
- Then tap Siri
- At the bottom you will see a switch called “Raise to Speak”. Turn it to “On” and you are all set.
