Understanding how the brain controls speech in healthy individuals
Behavioral and Neural Measures of Speech Motor Control
This study is trying to understand how healthy people control their speech by looking at how they adapt their speaking when they hear changes in their own voice.

What this trial studies
This research aims to explore the cognitive, perceptual, and motor processes involved in speech control by studying healthy speakers. The study will enroll 329 participants over five years and consists of eight experiments focusing on how speech motor control is executed, maintained, and adapted under altered auditory feedback conditions. Participants will engage in various speaking tasks to assess how they perceive and adapt their speech sounds. The findings could provide insights into the mechanisms of speech perception and production.
Who should consider this trial
Good fit: Ideal candidates are English-speaking adults with normal hearing and speech, and no history of neurological conditions.
Not a fit: Patients with neurological disorders, hearing impairments, or those who are non-English speakers may not benefit from this study.
Why it matters
Potential benefit: If successful, this research could enhance speech rehabilitation techniques for individuals with speech disorders.
How similar studies have performed: Other studies have shown promise in understanding speech motor control, but this specific approach to sensorimotor adaptation is relatively novel.
