SpeechRecognitionResult.item()

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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;
}
