The start
event of the Web Speech API SpeechSynthesisUtterance
object is fired when the utterance has begun to be spoken.
Bubbles | No |
Cancelable | No |
Target objects | SpeechSynthesisUtterance |
Interface | SpeechSynthesisEvent |
Examples
utterThis.onstart = function(event) { console.log('We have started uttering this speech: ' + event.utterance.text); }
Inheritance
The start
event implements the SpeechSynthesisEvent
interface, which inherits from Event
. It therefore has available the properties and methods defined on both these interfaces.
