A number.
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; console.log(event.results.length); };
