Can ultrasound help kids speak clearly? new trial tests it
NCT ID NCT06831396
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using ultrasound to show tongue movements on a screen can help children with speech sound disorders pronounce sounds better. Sixty children will be randomly assigned to get the therapy right away or wait a few weeks. The goal is to see if this visual feedback makes articulation therapy more effective.

- What this could lead to
- If it works, this could provide a new, non-invasive way to help children with speech sound disorders speak more clearly.
- What could go wrong
- This is a small, early-stage study with only 60 children. The ultrasound technique may not work for everyone, and results may not apply to all types of speech disorders.
