SpeechRecognition: soundstart event
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The soundstart event of the Web Speech API is fired when any sound — recognizable speech or not — has been detected.
Syntax
Use the event name in methods like addEventListener(), or set an event handler property.
js
addEventListener("soundstart", (event) => { })
onsoundstart = (event) => { }
Event type
A generic Event with no added properties.
Examples
You can use the soundstart event in an addEventListener method:
js
const recognition = new (SpeechRecognition || webkitSpeechRecognition)();
recognition.addEventListener("soundstart", () => {
console.log("Some sound is being received");
});
Or use the onsoundstart event handler property:
js
recognition.onsoundstart = () => {
console.log("Some sound is being received");
};
