Visual Feedback Effects on Speech Motor Adaptation in Healthy Adults

This study is looking at how adding visual information might help people adjust their speech. Researchers are using Altered Auditory Feedback (AAF), where you hear your own speech differently through headphones, and Visual-Acoustic Biofeedback, which adds a real-time visual display of your speech. They want to see if how much you rely on hearing versus physical sensations when you speak can predict how much the visual display helps you adapt. This study is for healthy adults aged 18-45 who speak English as a dominant language and have no history of significant speech, language, or hearing difficulties. The main goal is to measure the difference in how much people adjust their speech when using both auditory and visual feedback compared to just auditory feedback. The current status of this study is unclear, and it plans to enroll 40 participants.

Study design
This is an interventional study involving 40 healthy adult participants. It compares two behavioral interventions: Altered Auditory Feedback and Visual-Acoustic Biofeedback.
What's involved
You would produce speech while hearing altered feedback through headphones, sometimes with an added visual display of your speech. This takes place during a single study visit.
Compensation
Not stated in the trial record.
Follow-up
The primary outcome is measured during the study visit on Day 1, so there is no extended follow-up.

Eligibility criteria

Inclusion

Age 18 to 45 years
Self-reported English as dominant or equally dominant language (learned English by age 3)
No self-reported history of significant speech, language, or hearing difficulty
Pass pure-tone hearing screening at 25 dB HL
Pass qualitative screening of speech, voice, and resonance based on connected speech sample

Exclusion

Learned English after age 3
English is not a dominant language
History of speech or language disorder, hearing loss, or neurodevelopmental disorder (e.g., autism spectrum disorder, Down syndrome)
Failure to pass pure-tone hearing screening
Failure to pass qualitative screening of speech, voice, and resonance

What this trial measures

  • Mean difference in F1 compensation magnitude between auditory-visual and auditory-only feedback conditions of standard adaptive feedback taskDuring study visit (Day 1)

    Visual gain is defined as the within-participant difference in acoustic compensation magnitude (measured from formant frequencies) between the auditory-visual feedback condition and the auditory-only condition of the standard adaptive feedback task. Greater visual gain indicates a larger compensatory response when visual feedback is available.
