ISCA organizes special events in which a special effort is made to gather scientists doing research on specific topics. This sequence of workshops, previously known as ETRWs (ESCA Tutorial & Research Workshops) because of their former European origin, plays an important role in bringing speech scientists together. The tutorial presentations give advanced aspects of the topics that could especially benefit industrial attendees wanting an overview of the state-of-the-art in that field from international specialists. ISCA also finds it important to co-sponsor other specialized workshops focused on a research topic of interest.
