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 recognized');
}
