Visual Feedback for Speech
(PVF Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This study examines whether individual differences in how speakers respond to hearing versus physical sensation during speech can predict who benefits most from visual feedback during a speech task. Healthy adults will complete a series of tasks in which auditory feedback is altered in real time through headphones, with and without an added visual display of the speech signal. A computational model will be used to estimate how strongly each participant relies on hearing versus physical sensation when monitoring speech. The study will then test whether this individual profile predicts how much the visual display improves each participant's ability to respond to the altered feedback.

Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Baseline
Participants complete two versions of an altered auditory feedback task without visual feedback to estimate auditory and somatosensory response parameters.
Treatment
Participants complete a standard adaptive altered auditory feedback task with simultaneous real-time visual-acoustic biofeedback.
Follow-up
Participants are monitored for any delayed effects or additional data collection post-treatment.
What Are the Treatments Tested in This Trial?

Experimental Treatment
All participants complete altered auditory feedback tasks without visual feedback (baseline phase) followed by the same task with simultaneous real-time visual-acoustic biofeedback. Both conditions are administered within a single study visit.
