# Improve intelligibility of Parkinson speech

**Goal (in five words):** Improve intelligibility of Parkinson speech

- **Status:** RECRUITING
- **Study Type:** INTERVENTIONAL

## Summary For Families

The goal is to help people with Parkinson's be better understood by training their conversation partners to recognize and manage the speech changes that make everyday conversation hard. The approach teaches listeners practical strategies like using context clues, asking targeted clarification questions, reducing background noise, and using visual or written cues so partners can follow speech more easily, without changing the person’s medications or the speaker’s voice. The study is looking for adults 18 and older with a medical diagnosis of Parkinson's and a speech diagnosis of dysarthria, who are primary English speakers and do not have severe cognitive impairment.
