Summary

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.

Interventions

BEHAVIORAL

Altered Auditory Feedback (AAF)

Participants produce speech while hearing real-time altered auditory feedback delivered through headphones. Two task variants are administered: a fast-adapt design in which the altered feedback is introduced and withdrawn repeatedly, and a standard adaptive design in which the altered feedback is introduced once and maintained for an extended run. Administered to all participants as the baseline condition.

BEHAVIORAL

Visual-Acoustic Biofeedback

Participants perform the standard adaptive auditory feedback task with the addition of real-time visual display. The visual display presents the altered auditory signal alongside a visual target derived from the participant's baseline production. Administered to all participants following the auditory-only baseline phase.
