The iPhone, iPad, and iPod touch can listen for the words “Hey Siri” to start the personal voice assistant. How can I turn on Hey Siri on my device?
The “Hey Siri” option will let you activate your Apple device with just a simple phrase. Tap Settings > Siri & Search and make sure the Listen for ‘Hey Sar’ slider is turned ON (green). Now say “Hi” when using this feature so that she knows who’s asking!
