SpeechRecognitionEvent

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The SpeechRecognitionEvent interface of the Web Speech API represents the event object for the result and nomatch events, and contains all the data associated with an interim or final speech recognition result.

Constructor

SpeechRecognitionEvent(): Creates a new SpeechRecognitionEvent object.

Instance properties

SpeechRecognitionEvent also inherits properties from its parent interface, Event.

SpeechRecognitionEvent.resultIndex Read only: Returns the lowest index value result in the SpeechRecognitionResultList "array" that has actually changed.
SpeechRecognitionEvent.results Read only: Returns a SpeechRecognitionResultList object representing all the speech recognition results for the current session.

Examples

This code is excerpted from our Speech color changer example.

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