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 error event of the Web Speech API SpeechSynthesisUtterance object is fired when an error occurs that prevents the utterance from being succesfully spoken.

utterThis.onerror = function(event) { console.log('An error has occurred with the speech synthesis: ' + event.error); }
The error event implements the SpeechSynthesisErrorEvent interface, which extends the SpeechSynthesisEvent interface, which in turn inherits from Event. It therefore has available the properties and methods defined on all these interfaces.
