For Interspeech 2013 in Lyon, we launched a first version of a mobile phone app, which should support conference participants prior to and during the conference. We anticipated that the app will be of use to conference organizers alike, and that it could be turned into an open-source tool for the spoken language technology community. In this contribution, we will demonstrate usage experiences collected during the 2013 and 2014 Interspeech conferences, and propose and implement ideas for carrying out speech research with such an app.
