SpeechRecognition: result event
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.

The result event of the Web Speech API is fired when the speech recognition service returns a result — a word or phrase has been positively recognized and this has been communicated back to the app
Syntax
Use the event name in addEventListener():
js
addEventListener("result", (event) => { })
Alternatively, assign to the event handler property of the interface:
js
onresult = (event) => { }
Event type
A SpeechRecognitionEvent. Inherits from Event.
Examples
This code is excerpted from our Speech color changer example.
You can use the result event in an addEventListener method:
js
const recognition = new SpeechRecognition();
recognition.addEventListener("result", (event) => {
const color = event.results[0][0].transcript;
diagnostic.textContent = `Result received: ${color}.`;
bg.style.backgroundColor = color;
});
Or use the onresult event handler property (but note that this replaces other event listeners added using onresult, if any):
js
recognition.onresult = (event) => {
const color = event.results[0][0].transcript;
diagnostic.textContent = `Result received: ${color}.`;
bg.style.backgroundColor = color;
};
