How AI Lives Inside Alexa, Siri, and Google Home

Smart speakers have AI ears that listen for your wake word.

5 min · Reviewed 2026

The big idea

Alexa, Siri, and Google Home all have AI inside. They sit quietly until they hear their special name (the 'wake word'). Then they zoom your voice to faraway computers to figure out what you want.

Some examples

Alexa wakes up when it hears 'Alexa'.
Siri wakes up for 'Hey Siri'.
Google wakes up for 'Hey Google'.
If they hear something close to their name, they sometimes wake by accident!

Try it!

With a grown-up, ask a smart speaker to set a 1-minute timer. Notice how it 'thinks' for a second before answering.

Practice this safely

Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about smart speakers, not to let it make the decision for you.

Ask AI to explain smart speakers in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "How AI Lives Inside Alexa, Siri, and Google Home" and ask for two possible next steps plus one reason each step might be wrong.
Check wake word against a trusted source, teacher, adult, expert, or original document before you use it.
