This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.
The onnomatch
property of the SpeechRecognition
interface represents an event handler that will run when the speech recognition service returns a final result with no significant recognition (when the nomatch
event fires.)
This may involve some degree of recognition, which doesn't meet or exceed the confidence
threshold.
Note: The onnomatch
handler does not yet work properly in Firefox — the speech recognition system always returns a positive match, and then guesses at what item in the grammar it found. This is being worked on.
Syntax
mySpeechRecognition.onnomatch = function() { ... };
Examples
var recognition = new SpeechRecognition();
recognition.onnomatch = function() {
console.log('Speech not recognised');
}
