SpeechRecognitionEvent: resultIndex property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The resultIndex read-only property of the
SpeechRecognitionEvent interface returns the lowest index value result in
the SpeechRecognitionResultList "array" that has actually changed.
The SpeechRecognitionResultList object is not an array, but it has a
getter that allows it to be accessed by array syntax.
Value
A number.
Examples
js
recognition.onresult = (event) => {
const color = event.results[0][0].transcript;
diagnostic.textContent = `Result received: ${color}.`;
bg.style.backgroundColor = color;
console.log(event.resultIndex); // returns 0 if there is only one result
};
