Many thanks to all who submitted presentation proposals for this collaborative event. We are delighted with the enthusiastic response to the Call for Papers! Proposals are now being evaluated by the review committees, and corresponding authors will be informed of the outcome of the review process during February.




One World, Many Voices: Science and Community, the Inaugural Joint World Congress of the International Cluttering Association, International Fluency Association, and International Stuttering Association, is a ground-breaking initiative with seemingly diverse groups cooperating effectively to explore stuttering and cluttering. The theme of the upcoming congress resonates with our shared belief that worthwhile advances in quality of life and advocacy for those living with fluency disorders occur best in the context of open dialogue and mutual respectful exchange among people who stutter or clutter, therapists seeking to help, and researchers seeking to understand the nature of fluency disorders and best intervention practices.

This congress will, therefore, include a variety of presentation and workshop types, with a focus on high-quality research, advances in quality of life, and social opportunities promoting contact and networking both within and across the diverse groups. Although only presentations and workshops of the highest standards will be accepted for inclusion in the program, sessions aimed at either specific audiences, or at all the groups involved in this collaborative congress are welcome.


Types of proposals
We invite presentation proposals on a wide variety of topics related to stuttering, cluttering, and other fluency disorders. Suitable topics include, among others, etiology and development of stuttering and cluttering, living with stuttering and cluttering, therapy, support, advocacy and empowerment, workplace and disability issues, as well as opportunities for networking and socializing. Proposals on the topic of introducing therapy for stuttering in Japan are also welcome.

Proposals may be submitted in English or Japanese although, due to the international nature of the congress, English is encouraged whenever possible.

Proposals for oral and poster presentations are now invited in the categories outlined below. The categories do not necessarily reflect different streams within the congress but, rather, are intended to ensure that proposals can be allocated to the most appropriate Review Committee. You should select the category you feel best corresponds to your proposal. The Program Committee reserves the right to send proposals to an alternative Review Committee if this is deemed appropriate during the review process.


Advocacy and Empowerment


Living with stuttering and cluttering


Presentations and workshops exploring aspects of equality, social justice, social change, workplace and disability issues.

All presentations with a primary focus on describing or discussing research projects, proposals or theories related to stuttering, cluttering or other fluency disorders should be submitted to this category.

Presentations and workshops exploring the lived experience of stuttering and cluttering, sharing experiences, self-identity, common themes and differing viewpoints. Opportunities to network, learn new skills, make new friends and reconnect with old ones are also welcome in this submissions category.

Presentations and workshops describing aspects of therapies, interventions or activities addressing various aspects of stuttering and cluttering.

The following presentation formats are available:

  • 30-minute oral presentation
  • 60-minute oral presentation
  • 90-minute oral presentation
  • Poster presentation

Oral presentations should allow 5-10 minutes for questions and discussion at the end (which should be included within the timescales stated above). While all categories are eligible for all durations, a research update may be particularly well-suited to a 30-minute presentation, whereas the longer 60- and 90-minutes sessions may be appropriate for workshops, seminars, panel discussions and more detailed research presentations.

Simultaneous translation (English-Japanese and Japanese-English) will be provided for all plenary sessions, and for some parallel sessions.

Poster presentations provide a visual summary of a project or other information, and create the opportunity for delegates to interact and engage in one-to-one discussions with the presenters. While poster presentations typically showcase research projects, their format can be adapted to meet the needs of other types of projects. There are guidelines regarding the layout of poster presentations, so those unfamiliar with such conventions are advised to seek this information. Please note that, while proposals for posters may be submitted in English or Japanese, those accepted by the relevant Review Committee must be printed in English for inclusion in the poster sessions during the congress itself. During the poster sessions, poster presenters are encouraged to have handouts of their posters available in Japanese if possible.

Language use
As this is a collaborative congress, hosting people affiliated with a variety of organizations, roles and viewpoints within the stuttering and cluttering community, we request that presenters consider their use of language, recognizing that while there are valid reasons for the use of particular terms within particular contexts, specific terms or ways of describing individuals, groups or processes may be used and understood differently within other contexts. 

Some general examples and recommendations are given below, but the use of these terms or others is left entirely to the discretion of the individual.

  • “Fluency disorders” can be used as a general term to refer to stuttering, cluttering and other fluency disorders. The term "disorder" is not intended to indicate anything regarding an individual’s character or abilities. The term is considered necessary to facilitate a common language for researchers, therapists and PWS/PWC, and also to facilitate access to health insurance for those needing or wanting therapy.
  • People who stutter (PWS), Children who stutter (CWS), People who clutter (PWC) and Children who clutter (CWC) can be used in preference to “consumers” or “clients.”
  • Therapists, Speech Language Pathologists (SLPs) and Researchers can be used in preference toprofessionals” or “experts”. We consider that PWS and PWC are also experts on their own stuttering/cluttering, and have an intimate knowledge of it. In addition, PWS and PWC should be an integral part of any therapeutic process, as opposed to simply being passive accepters of therapeutic guidelines. The therapeutic process is something that should be built together and should be based in mutual confidence and sharing of points of views, personal experience and, of course, scientific knowledge.

Submission of proposals
Submission of a proposal is a commitment by at least one of the authors to register for the congress and present in the time slot assigned by the Organizing Committee. Receipt of submitted proposals will be acknowledged within a week via an electronic receipt including a submission reference number.  The deadline for submissions is 15th December, 2017.

Selection criteria/guidelines
Submissions will be anonymized and sent for review. Review committees will conduct a peer review of the content of each proposal to assess its quality, relevance to the congress, clarity, originality, timeliness, and compatibility. Proposals seeking ASHA-approved continuing education credits will be subject to a further review to ensure they meet the necessary criteria.

Submissions will be evaluated by the Review Committee during early 2018. Papers will be selected for inclusion in the program on the bases of quality, type of proposal, nature of proposal, relevance to conference participants and scheduling constraints.  The corresponding author will be notified of acceptance status by 18th February 2018.

Continuing Education Units (CEUs)
Continuing Education Units, also known as CEUs, are a standard unit of measurement for participation in a learning event. CEUs provide a way in which individuals working in certain professions can evidence their continuing professional development, and highlight presentations which demonstrate dedication to education and a commitment to excellence, in meeting the CEU criteria.

Application is being made to offer ASHA (American Speech-Language-Hearing Association) CEUs for this congress through the University of Maryland College Park - an approved ASHA CEU provider. To be eligible for ASHA CEUs, the presentation content and learning outcomes must contribute to the acquisition of new skills and knowledge for delegates, and must be related to speech sciences, or the contemporary practice of speech-language pathology in some way.

Application for CEU approval is strongly encouraged. Authors interested in applying for CEU approval for their presentation should complete the relevant sections on the Presentation Proposal Form. For CEU submissions, references to relevant research are strongly encouraged. The Presentation Proposal Form describes the information required to apply for CEU approval. Unfortunately, the link included in the form leading to examples of how to write Learner Outcomes is no longer working, so a new link is included here: How_to_write_Learner_Outcomes.pdf 

Presentations seeking CEU approval will be evaluated by a CEU Committee, and corresponding authors will be informed of the outcome of this evaluation in due course.


Scheduling of presentations
The Organizing Committee will allocate presentation time slots and it is not possible for presenters to request a specific slot. Of the presentations which are accepted for inclusion in the congress program, some will be scheduled to follow key speakers as part of the morning plenary sessions of the congress, whereas others will be included within the afternoon parallel sessions.

Upon conclusion of the conference, all presenters can submit their paper/presentation to be published in the peer-reviewed online proceedings of the 2018 One World, Many Voices: Science and Community Joint World Congress. A special edition of the American Journal of Speech-Language Pathology is also under discussion.

Application has been made to support student and junior faculty World Congress travel and accommodation to the US National Institute on Deafness and Other Communication Disorders (NIDCD). Its recent review was very favorable. Although no firm commitments can be made until NIDCD Council meets in late January 2018, we are optimistic, given its very positive review score,  that a bursary to support student and junior faculty attendance at the World Congress will be made available in early spring. This award would also sponsor a separate series of educational seminars) to aid younger researchers in grant preparation and manuscript publication. Once funding is confirmed, applications for travel support will be made available and review will occur quickly to ensure best support for junior researcher attendance at the World Congress. Awardees will also be granted a waiver of the congress registration fee.

The International Fluency Association (IFA) is also offering its members who are in financial need the opportunity to apply for bursaries to assist with the costs of congress registration and travel. The IFA bursary scheme will be open for applications from full IFA members, who have had a presentation accepted for inclusion in the congress programme, and who are planning to attend the four days of the congress. Further details of the application and review process will be made available in due course.

The other organisations involved in the collaboration are currently considering the possibility of offering similar schemes for their members. Information will be published on the congress website as it becomes available.

In addition, we have applied to the National Institutes for Health (USA) for travel funding support for students and researchers. The National Institutes for Health will inform us of their decision toward the end of November 2017. More information regarding this potential source of funding will be made available at that time.
