One World, Many Voices: Science and Community is the Inaugural Joint World Congress of the International Cluttering Association (ICA), International Fluency Association (IFA) and International Stuttering Association (ISA), with local host organizations the Japan Society of Stuttering and Other Fluency Disorders and the Japanese Stuttering Genyukai Organization. This event will be held in Hiroshima, Japan, from the 13th to the 16th of July, 2018.

This exciting new collaboration between the three international organizations, and their Japanese hosts, aims to create an event that will allow everyone – people who stutter and clutter, their families and friends, clinicians, and researchers - to feel welcome, included and valued.

The Inaugural Joint World Congress will be a ground-breaking initiative where historically diverse groups are cooperating effectively to explore experiences of, feelings about, and attitudes towards stuttering and cluttering. We want people who stutter or clutter to feel safe and surrounded by friends. We want those who work clinically to have opportunities to share and update their skills. We want to give researchers an opportunity to present high-quality research in a stimulating environment, while simultaneously giving those who explore innovative and new approaches to living with stuttering and cluttering a chance to share their experiences and ideas.

The benefit of this cooperation will be entirely mutual and shared by people who stutter, people who clutter, clinicians, and researchers.

Please join us in Hiroshima, 13th to 16th of July, 2018!
