How it works

ListenSpeechRecognition streams words as you speak, and the final phrase is passed on when you pause.
UnderstandA small parser finds the action (on, off, set, lock), the device and any number in the phrase.
Act and replyThe device card updates, the log records the command, and the page speaks a short confirmation.

const SR = window.SpeechRecognition || window.webkitSpeechRecognition;
const rec = new SR();
rec.lang = "en-US";
rec.interimResults = true;

rec.onresult = (e) => {
  const r = e.results[e.results.length - 1];
  if (r.isFinal) handle(r[0].transcript); // "turn on the fan"
};
rec.start();

// Talk back
speechSynthesis.speak(new SpeechSynthesisUtterance("Fan is on"));
