Not applicable Interventional Arizona State University · NCT06181149

This study is testing how people who stutter process sounds and how it affects their speech to find new ways to help them communicate better.

What this trial studies

This study investigates how individuals who stutter process auditory information and how this affects their speech. Participants will engage in various tasks, such as naming pictures and reading aloud, while their speech and brain activity are monitored. The study aims to explore the role of auditory feedback and brain stimulation in speech production, providing insights that could lead to new interventions for stuttering. By analyzing the neural and behavioral responses, researchers hope to establish a foundation for future therapies.

Who should consider this trial

Good fit: Ideal candidates for this study are monolingual, native English speakers who experience developmental stuttering but do not have other communication or neurological disorders.

Not a fit: Patients with additional developmental, psychological, or neurological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to innovative treatments that improve communication skills and quality of life for individuals who stutter.

How similar studies have performed: While the specific approach of this study may be novel, previous studies have shown promise in using auditory feedback and brain stimulation techniques to address speech disorders.
