Summary

This study tests a smartphone app called Repeech designed to help people whose speech is slurred after a stroke. The app provides personalized speech therapy exercises, and researchers will compare its effectiveness to a standard workbook. The goal is to see if the app can improve how clearly participants are understood by others.

What this could mean

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

Active substance
Repeech digital therapeutic application
What this could lead to
If effective, Repeech could offer a convenient, home-based therapy option to improve speech clarity for stroke survivors with dysarthria.
What could go wrong
This is a mid-stage trial with 108 participants, so results may not apply to everyone. The app may not work better than traditional workbook exercises, and individual results will vary.
