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.

Event SpeechRecognitionEvent

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;
};
