NCT ID NCT06884943
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether an AI-powered app can help children aged 9 to 17 with speech sound disorder (trouble saying the /r/ sound) keep improving after speech therapy. About 76 kids will use the app at home to practice words, syllables, and sentences. The goal is to see if the AI tool helps them speak more clearly in everyday conversation.
