Thank you for your feedback. We are working on Intelligent Speaker's improvement. Please, note that it's a BETA version and there is still some space for new functionalities and bugfixing. If you could provide us more a detailed feedback we would be able to plunge into details and help you to figure out all the issues. Feel free to contact us [email protected] or via our social media: facebook: https://www.facebook.com/IntelligentSpeaker/ or twitter: https://twitter.com/IntSpeakerApp

UPDATE: now you can change the playback speed. And "announcement at the start" was rid off.
