Our project has put together virtual conference papers which document the outcome of the transnational seminar between Cologne (Universität zu Köln, IfL Phonetics) and Paris (Université de Paris): "Proceedings of the international Paris-Cologne seminar on Variability in Speech Production and Perception". In international groups, the experiments themselves were planned and possible outcomes were derived based on research literature and hypotheses; however, they were not carried out in the real world of experimental linguistics – not yet.
