SpeechRecognition: nomatch event - Web APIs 编辑

Experimental

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The nomatch event of the Web Speech API is fired when the speech recognition service returns a final result with no significant recognition.

This may involve some degree of recognition, which doesn't meet or exceed the confidence threshold.

Examples

You can use the nomatch event in an addEventListener method:

var recognition = new webkitSpeechRecognition() || new SpeechRecognition();

recognition.addEventListener('nomatch', function() {
  console.log('Speech not recognized');
});

Or use the onnomatch event handler property:

recognition.onnomatch = function() {
  console.log('Speech not recognized');
}
