"Hey Siri!" "Alexa!" How does a device wait, silently listening, for a special word — then follow your spoken commands? Let's turn on a real voice AI (running on your device!) and drive a robot with your voice.
This loads a small on-device AI trained to recognize spoken words like up, down, left, right, go, stop. It listens right in your browser — your voice never leaves your device. 🛡️ (First time downloads a few MB; then it's cached.)
Say "go" to wake the robot, then say "up", "down", "left", "right" to move it. Collect all 3 ⭐! (No mic? The arrow pad works too.)
You built a real voice-command system: a wake word that listens politely, then spoken commands that make things happen — all on your device. That's the core of every voice assistant and smart toy.
