Summary

This study tests whether specific voice therapy tasks can improve voice quality in 220 older adults with age-related voice changes (presbylarynx). Participants perform exercises like abdominal breathing, pushing tasks, and loud speaking. Researchers measure voice quality through video of the vocal cords and listener ratings. The goal is to find which exercises work best and for whom.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Voice therapy (behavioral tasks: abdominal voice onset, pulling/pushing, assertive, semi-occluded vocal tract)
What this could lead to
If successful, this could lead to simple, non-invasive voice exercises that help older adults speak more clearly and with less effort.
What could go wrong
This is a behavioral study without a control group, so improvements may be due to practice or natural variation. Results may not apply to everyone with voice problems.

Participants

About 220 people

The number the study aims to enrol. It can still change while the study runs.

Started

Apr 2019

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
