I would like to ask if there is any method that get called (and I can use) so get notified once the narrator has finish (reach the end of text). I am using OpenEars for very simple app and simply calling say:withVoice: passing the necessary string value.

In addition, I am wondering if there is any method to stop the narrator before reach the end of text.

Thanks in advance!

You can use the OpenEarsEventsObserver delegate method fliteDidFinishSpeaking to receive a callback when speech has completed (check out the OpenEarsEventsObserver section of the tutorial or its section in the PDF docs). FliteController can’t interrupt speech via a public API method but you can try sending [self.fliteController interruptTalking] which should stop speech.
