Study Details

The purpose of this research study is to understand how the brain processes and controls speech in healthy people. The investigators are doing this research because it will help identify the mechanisms that allow people to perceive their own speech errors and to learn new speech sounds. 117 participants will be enrolled into this part of the study and can expect to be on study between 1 day (Experiment 1) and 4 weeks (Experiment 2).
