The item
getter of the
SpeechRecognitionResult
interface is a standard getter that allows
SpeechRecognitionAlternative
objects within the result to be accessed via
array syntax.
Syntax
var myAlternative = speechRecognitionResultInstance[0];
Returns
A SpeechRecognitionAlternative
object.
Examples
This code is excerpted from our Speech color changer example.
recognition.onresult = function(event) {
// The SpeechRecognitionEvent results property returns a SpeechRecognitionResultList object
// The SpeechRecognitionResultList object contains SpeechRecognitionResult objects.
// It has a getter so it can be accessed like an array
// The first [0] returns the SpeechRecognitionResult at position 0.
// Each SpeechRecognitionResult object contains SpeechRecognitionAlternative objects
// that contain individual results.
// These also have getters so they can be accessed like arrays.
// The second [0] returns the SpeechRecognitionAlternative at position 0.
// We then return the transcript property of the SpeechRecognitionAlternative object
var color = event.results[0][0].transcript;
diagnostic.textContent = 'Result received: ' + color + '.';
bg.style.backgroundColor = color;
}
