Simple breathing gadgets may save Professors' voices
NCT ID NCT07371351
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether two breathing exercise devices, EMST and Triflo, can reduce voice fatigue and improve voice quality in academics who teach a lot. Forty participants will use the devices for 5 weeks, and their voice measurements and fatigue scores will be tracked. The goal is to see if these simple exercises can help prevent voice problems in people who rely on their voices for work.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Expiratory Muscle Strength Trainer (EMST 150) and Triflo breathing exercise device
- What this could lead to
- If it works, this could point toward a simple, drug-free way to prevent or ease voice fatigue in people who use their voice a lot at work.
- What could go wrong
- This is a very small, early study with only 40 participants. It is not yet recruiting, and results may not apply to everyone. The devices are not treatments for serious voice disorders.
