Speech Signals in Stuttering

The purpose of this research study is to understand how speech and language are processed in the brain. This study will provide information that may help with the understanding how speech and language are processed in children and whether there may be differences between children who stutter and children who do not stutter. This project will evaluate these neural processes for speech signals in children who stutter and control subjects through a battery of behavioral speech and language tests, electroencephalography-based (EEG) tasks, functional magnetic resonance imaging (fMRI), and computational modeling.
