NCT ID NCT07599696
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether speech amplification devices can help people with Parkinson's disease and related conditions who have a soft, weak voice (hypophonia). Researchers will work with 100 participants to measure how well these devices improve speech loudness, clarity, and understanding. They will also explore ways to personalize the device settings for each person's needs.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- speech amplification device and behavioral speech strategies
- What this could lead to
- If successful, this could provide a personalized, non-drug way to improve speech loudness and clarity for people with Parkinson's disease.
- What could go wrong
- This is an early-stage study with only 100 participants, so results may not apply to everyone. The devices may not work for all types of voice changes.
