The mark
event of the Web Speech API SpeechSynthesisUtterance
object is fired when the spoken utterance reaches a named SSML "mark" tag.
Bubbles | No |
Cancelable | No |
Target objects | SpeechSynthesisUtterance |
Interface | SpeechSynthesisEvent |
Examples
utterThis.onmark = function(event) { console.log('A mark was reached: ' + event.name); }
Inheritance
The mark
event implements the SpeechSynthesisEvent
interface, which inherits from Event
. It therefore has available the properties and methods defined on both these interfaces.
