Your phone listens in on your conversations. It uses a tiny microphone that's always on, even when you're not using it. When you start talking, the phone hears your voice and knows it’s time to record or respond, like how your friend can tell when you’re starting to talk in class.
Examples
- Your phone hears your voice even when you're shouting across the room at your sibling.
- It knows when you start talking because it listens all the time, like a friend waiting for you to say something in class.
- Sometimes it thinks you're talking when you're just eating cereal or chewing gum.
