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.
A number.
recognition.onresult = function(event) { var 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 }
