This research is being done to better understand stuttering, specifically how people who stutter may process and/or produce speech. Eligible participants enrolled will complete a variety of computer and speech-based tasks on up to 2 visits.
The study team will update the record to include the secondary identification number once the NIH has released the funds.

| Measure | Description | Time Frame |
|---|---|---|
| Phase locking value (PLV) - Session 1 speech tasks | The degree of synchronization will be measured by computing the PLV between subject's produced speech and the heard speech. The PLV is a vector with a value between 0 and 1 that reflects the phase difference between two signals. | Session 1 (up to 4 hours) |
| Phase locking value (PLV) - Session 2 speech tasks | The degree of synchronization will be measured by computing the PLV between subject's produced speech and the heard speech. The PLV is a vector with a value between 0 and 1 that reflects the phase difference between two signals. Session 2 is for adults only. | Session 2 (up to 4 hours) |
| Measure | Description | Time Frame |
|---|---|---|
| Phase locking value (PLV) - Non-speech tasks | The degree of synchronization will be measured by computing the PLV between subject's produced response and the auditorily presented stimuli. The PLV is a vector with a value between 0 and 1 that reflects the phase difference between two signals. | Session 1 (up to 4 hours) |
