SpeechRecognitionResult.isFinal
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The isFinal
read-only property of the
SpeechRecognitionResult
interface is a boolean value that states
whether this result is final (true
) or not (false
) — if so,
then this is the final time this result will be returned; if not, then this result is an
interim result, and may be updated later on.
Syntax
var myIsFinal = speechRecognitionResultInstance.isFinal;
Returns
A boolean value.
Examples
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;
console.log(event.results[0].isFinal);
}
