Siri is Apple's personal assistant for iOS and its other devices that uses voice recognition and is powered by artificial intelligence. It responds to users' spoken questions by speaking back to them through the device's speaker, and presenting relevant information on the home screen from certain apps. If your iPhone S-E 3 doesn’t respond to your voice, it’s because Siri might need to be set up properly first. That’s what we’re going to show you in this video, but before anything else, please like and share our video so we can help other users as well.
