Hi Richa,
If you’d like help with your issues, please take a look at this post:
https://www.politepix.com/forums/topic/install-issues-and-their-solutions/
And show the code that you have written. I am happy to help but it isn’t possible to give help with an issue like this without any information about your code and what you have tried already, since the fliteDidFinishSpeaking delegate function is known to work.
When you show your code, please show the parts where you set the delegate of OpenEarsEventsObserver. Thanks!
