Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.

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.
Syntax
Use the event name in methods like addEventListener(), or set an event handler property.
js
addEventListener("nomatch", (event) => { })
onnomatch = (event) => { }
Event type
A SpeechRecognitionEvent. Inherits from Event.
Examples
You can use the nomatch event in an addEventListener method:
js
const recognition = new (SpeechRecognition || webkitSpeechRecognition)();
recognition.addEventListener("nomatch", () => {
console.error("Speech not recognized");
});
Or use the onnomatch event handler property:
js
recognition.onnomatch = () => {
console.error("Speech not recognized");
};
