Imagine your smartphone is like a friend who listens to you talk. It has tiny ears, called microphones, that can hear your voice and tell if you're speaking or not. When you start talking, it knows to pay attention and record what you say. The phone uses something called sound waves, which are invisible vibrations in the air, to figure out when you begin speaking. It's like a game of hide-and-seek: your voice is the seeker, and the phone is looking for it!
Examples
- Your phone knows when you're talking because it hears your voice, just like how a friend listens to you in conversation.
- Even if you're speaking quietly in a noisy room, the phone can still figure out that you're talking.
