Smartphones have a special kind of listening power. It's like having a friend who can hear you even if it's loud outside. When you say, 'Hey Siri,' your phone hears the sound and knows to respond right away, just like when someone says your name in a crowd.
Examples
- Smartphone hears 'Hey Siri' and says, 'What can I do for you?'
- Phone listens when you're asking it a question in a loud room.
- Voice assistant wakes up only when it hears your special word.
