SpeechRecognitionResultList: item() method

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The item getter of the SpeechRecognitionResultList interface is a standard getter — it allows SpeechRecognitionResult objects in the list to be accessed via array syntax.

Syntax

js
item(index)

Parameters

index

Index of the item to retrieve.

Return value

Examples

This code is excerpted from our Speech color changer example.

js
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;
};
