Predicting who benefits from visual feedback during speech tasks
Prediction of Visual Feedback Gain in Altered Auditory Feedback Tasks Using Computational Modeling
This test tries to see if adding a real-time visual display of the speech signal helps healthy adults adapt their speech when their auditory feedback is altered.

What this trial studies
Healthy adults will perform speech tasks in which what they hear through headphones is altered in real time, first without and then with an added visual display of the speech signal. A computational model will estimate for each participant how much they rely on auditory versus physical (somatosensory) feedback when monitoring speech. The study compares baseline performance to performance with visual-acoustic biofeedback to measure how much the display improves adaptation to altered auditory feedback. The primary goal is to see whether an individual's sensory-weighting profile predicts how much they benefit from the visual display.
Who should consider this trial
Good fit: Healthy adults aged 18 to 45 who learned English by age 3, report no history of speech, language, or hearing problems, and pass hearing and speech screenings are ideal candidates.
Not a fit: People with hearing loss, a history of speech or language disorders, neurodevelopmental conditions, or those who learned English after age 3 are excluded and unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, this work could help match visual biofeedback tools to the people most likely to benefit, making speech therapy and training more efficient.
How similar studies have performed: Previous research shows that altered auditory feedback and visual biofeedback can change speech motor adaptation and that computational models can estimate sensory weighting, so this study applies those methods to predict who benefits from visual feedback.
