The SpeechRecognitionResultList interface of the Web Speech API represents a list of SpeechRecognitionResult objects, or a single one if results are being captured in non-continuous mode.
SpeechRecognitionResultList.length Read only
Returns the length of the "array" â the number of SpeechRecognitionResult objects in the list.
SpeechRecognitionResultList.item
A 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.
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;
};
