Your voice may reveal hidden airway risks before surgery
NCT ID NCT07278232
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study explores whether the sound of your voice can help doctors predict if placing a breathing tube during surgery will be difficult. Researchers will record 300 patients saying vowel sounds before surgery and use machine learning to find voice patterns linked to airway anatomy. The goal is to create a quick, non-invasive screening tool to improve patient safety.
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, painless voice test to help doctors identify patients who may have a difficult airway before surgery.
What could go wrong
This is an early observational study with only 300 participants, so results may not apply to everyone. The voice patterns might not reliably predict difficult intubation in practice.
