NCT ID NCT05439447
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study from Seoul National University Hospital tested whether voice recordings and throat sensors can detect swallowing problems (dysphagia). Researchers collected voice samples from 259 adults before and after swallowing, comparing them with standard X-ray tests. The goal is to develop a non-invasive, machine-learning tool for diagnosis and monitoring, potentially replacing more uncomfortable procedures.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could lead to a simple, non-invasive voice-based test to help diagnose swallowing disorders without the need for X-ray exams.
What could go wrong
This is an early data-collection study, not a treatment trial. The voice analysis method may not prove accurate enough for clinical use.
