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 methods like addEventListener(), or set an event handler property.

addEventListener("result", (event) => { })

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:

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:

recognition.onresult = (event) => {
  const color = event.results[0][0].transcript;
  diagnostic.textContent = `Result received: ${color}.`;
  bg.style.backgroundColor = color;
};
