Speech Processing in Stuttering

Not Applicable

Completed

• Conditions: Stuttering, Adult; Stuttering, Childhood; Stuttering

• Registration Number: NCT04929184
• Lead Sponsor: University of Michigan

Brief Summary

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.

Detailed Description

The study team will update the record to include the secondary identification number once the NIH has released the funds.

Primary Outcome Measures

Name	Time	Method
Phase locking value (PLV) - Session 2 speech tasks	Session 2 (up to 4 hours)	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.
Phase locking value (PLV) - Session 1 speech tasks	Session 1 (up to 4 hours)	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.

Secondary Outcome Measures

Name	Time	Method
Phase locking value (PLV) - Non-speech tasks	Session 1 (up to 4 hours)	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.
