Interventions

  • Altered Auditory Feedback (AAF) — BEHAVIORAL
    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 Two task variants are administered: a fast-adapt design in which the altered feedback is introduced and withdrawn repeatedly, and a standard adaptive design in which the altered feedback is introduced once and maintained for an extended run.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.
  • Visual-Acoustic Biofeedback — BEHAVIORAL
    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.

Study Details

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.

Arms

  • Experimental: Altered Auditory Feedback With and Without Visual Feedback
    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.

Primary Outcome Measure

Mean difference in F1 compensation magnitude between auditory-visual and auditory-only feedback conditions of standard adaptive feedback task [ Time Frame: During study visit (Day 1) ]
