This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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.
Syntax
var myResultIndex = event.resultIndex;
Value
A number.
Examples
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 }
