SpeechRecognitionResult: item() method

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

item(index)

Parameters

index: Index of the item to retrieve.

Return value

A SpeechRecognitionAlternative object.

Examples

This code is excerpted from our Speech color changer example.

recognition.onresult = (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
  const color = event.results[0][0].transcript;
  diagnostic.textContent = `Result received: ${color}.`;
  bg.style.backgroundColor = color;
};
