onresult
特性为
SpeechRecognition
interface represents an event handler that will run when the speech recognition service returns a result — a word or phrase has been positively recognized and this has been communicated back to the app (when the
result
event
fires.)
mySpeechRecognition.onresult = function() { ... };
This code is excerpted from our Speech color changer 范例。
recognition.onresult = function(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
var color = event.results[0][0].transcript;
diagnostic.textContent = 'Result received: ' + color + '.';
bg.style.backgroundColor = color;
}
