[Question] Speech Synthesis onend method not called sometimes

[RichardsonWTR]

Hi!

At least, in Chrome the speech synthesis not call the onend method sometimes. I'm using Chrome 49.0.2623.87. I have faced this problem reproducing big messages.
See in Chromium Bugs.

I have found some workarounds, but nothing worked.

My workaround on this was to set a maximum time of audio reproduction, then I cancel the audios on queue.

window.speechSynthesis.speak(msg);
audio_timeout = setTimeout(function(){
    window.speechSynthesis.cancel();
},20000);

// And and when the onend method not fails, the timeout is cancelled
msg.onend = function(e) {
   clearTimeout(audio_timeout);
};

My question is: in this polyfill, do you have a workaround about it?
Cheers!

Hi @RichardsonWilliam

I have no idea, however onend is called when audio is stopped. So it could work. Feel free to try it.
