SpeechSynthesisUtterance: mark event
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2018.
The mark event of the Web Speech API SpeechSynthesisUtterance object is fired when the spoken utterance reaches a named SSML "mark" tag.
Syntax
Use the event name in addEventListener():
js
addEventListener("mark", (event) => { })
Alternatively, assign to the event handler property of the interface:
js
onmark = (event) => { }
Event type
A SpeechSynthesisEvent. Inherits from Event.
Examples
You can use the mark event in an addEventListener method:
js
utterThis.addEventListener("mark", (event) => {
console.log(`A mark was reached: ${event.name}`);
});
Or use the onmark event handler property (but note that this replaces other event listeners added using onmark, if any):
js
utterThis.onmark = (event) => {
console.log(`A mark was reached: ${event.name}`);
};
