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.
SpeechRecognitionEvent()Creates a new SpeechRecognitionEvent object.
SpeechRecognitionEvent also inherits properties from its parent interface, Event.
SpeechRecognitionEvent.resultIndex Read onlyReturns the lowest index value result in the SpeechRecognitionResultList "array" that has actually changed.
SpeechRecognitionEvent.results Read onlyReturns a SpeechRecognitionResultList object representing all the speech recognition results for the current session.
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;
};
