About this trial
Stuttering negatively impacts communication and reduces the overall quality of life and well-being of individuals who stutter. This study will provide a strong foundation for developing neural and behavioral interventions for stuttering. Participants will be asked to name pictures, read words/sentences silently or aloud, and listen to speech and nonspeech sounds while their speech, muscle, and brain signals are collected. Some participants may also receive brain stimulation while reading and speaking.
