SpeechRecognitionResultList.length Read only
Returns the length of the "array" — the number of SpeechRecognitionResult objects in the list.
SpeechRecognitionResultList.itemA standard getter that allows SpeechRecognitionResult objects in the list to be accessed via array syntax.
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; };
