AI Helpers — Siri, Alexa & Friends
Meet Your AI Helpers
Virtual assistants like Siri, Alexa, and Google Assistant are AI programs you can talk to out loud. They listen to your voice, understand what you're saying, and try to help.
You can ask them to:
- Answer questions ("What's the capital of France?")
- Set timers and reminders
- Play your favorite music
- Tell you the weather
- Tell jokes! 😄
- Control smart home devices like lights and thermostats
🎙️ These AI assistants understand billions of different ways people might ask the same question. That takes an enormous amount of learning!
How Do They Actually Work?
When you speak to Alexa or Siri, here's what happens in less than a second:
- Your voice is recorded by the microphone
- AI converts your spoken words into text
- Another AI reads the text and figures out what you mean
- It searches for the answer
- AI converts the answer back into speech and talks to you
All five of those steps happen almost instantly. That's pretty amazing!
Amazon Alexa can understand over 100,000 different commands and gets smarter every single day from new conversations.
