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.

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