Congress Theme 

After a long process of careful consideration and deliberation, the planning committee agreed on a theme: «One World, Many Voices: A Global Collaboration». 

This theme partially incorporates the theme of the founding congress held in Hiroshima in July 2018 («One World, Many Voices: Science and Community»), which was unanimous … or close to it! The theme of the 2021 congress is intended to bring people together («One World»), while encouraging the expression of different points of view («Many Voices»). 

The theme also fosters collaboration, not only between specialists and researchers, but especially between these same specialists and researchers and people who stutter or clutter. 

The Hiroshima event provided some indication that people who live with stuttering or cluttering should be given a significant voice in the organization of the congress. The subcommittee for the congress program took notice of this observation. 

It is anticipated that a sizeable portion of the program will be dedicated to workshops and presentations similar to those held during our networking events and at the National Stuttering Association congress, i.e., workshops by and for people who stutter or clutter. This is great news for ABC and its members, who will have the opportunity to submit workshop and presentation proposals.
