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 boundary event of the Web Speech API is fired when the spoken utterance reaches a word or sentence boundary.
| Bubbles | No |
| Cancelable | No |
| Target objects | SpeechSynthesisUtterance |
| Interface | SpeechSynthesisEvent |
Examples
utterThis.onboundary = function(event) {
console.log(event.name + ' boundary reached after ' + event.elapsedTime + ' milliseconds.');
}
Inheritance
The boundary event implements the SpeechSynthesisEvent interface, which inherits from Event. It therefore has available the properties and methods defined on both these interfaces.
