This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage 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 specification changes.

The mark event of the Web Speech API SpeechSynthesisUtterance object is fired when the spoken utterance reaches a named SSML "mark" tag.

Target objects SpeechSynthesisUtterance

Examples

utterThis.onmark = function(event) {
  console.log('A mark was reached: ' + event.name);
}
