SpeechRecognition.onresult
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The onresult
property of the 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.)
Syntax
mySpeechRecognition.onresult = function() { ... };
Examples
This code is excerpted from our Speech color changer example.
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; }
