The Speaker That Listens
Smart speakers are little AI helpers that wait for their name. Then they wake up, hear what you say, and answer back. Three big-name speakers are Alexa, Siri, and Google Assistant.
How it works (in 4 steps)
- 1It listens for the wake word (like "Hey Siri" or "Alexa")
- 2When it hears the word, it records what you say next
- 3It sends your voice to a big computer in the cloud
- 4The cloud computer thinks fast, then sends back an answer
Cool things they can do
- Set timers for cookies in the oven
- Tell jokes (some are pretty bad)
- Turn off lights without getting up
- Play your favorite song in 2 seconds
