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 webkitSpeechRecognition() || new SpeechRecognition();
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");
};
