This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
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 |
ExamplesEdit
utterThis.onmark = function(event) {
console.log('A mark was reached: ' + event.name);
}
InheritanceEdit
The mark event implements the SpeechSynthesisEvent interface, which inherits from Event. It therefore has available the properties and methods defined on both these interfaces.
