Day One (27th of September): Get introduced to Voice Applications and Google Assistant with hands-on evening sessions. You will learn how to design conversations, then deep-dive into different ways of building dialog flows. During this process, you will learn the best practices for developing your very first Voice Application. Join one of the hacking teams we put together, or bring a few friends and start your own. Afterwards, there will be time to network over snacks and drinks while you and your team brainstorm ideas for the next day’s hack.

Day Two (28th of September): We will turn ideas into actions by hacking your Voice Application with Google on Actions and Dialogflow. Special guest Dr.-Ing. Stefan Hillmann from TU Berlin's Quality and Usability Lab will be providing insights on state-of-the-art in voice research.
The local winning team will be announced on the same day and then compete globally for the grand prize

Throughout the entire event, experts will provide greater insight on specific topics, mentors will offer their support, and food & drinks will available whenever you’re in need
