Summary

This study tested whether adding biofeedback—using ultrasound or visual-acoustic displays—helps children aged 9 to 15 with speech sound disorder improve their /r/ sound more than traditional speech therapy alone. 108 children participated in a randomized controlled trial. The goal was to see if these high-tech tools lead to faster or greater gains in speech accuracy.

What this could mean

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

Active substance: biofeedback (ultrasound or visual-acoustic)
What this could lead to: If successful, this could point toward more effective speech therapy methods for children with persistent /r/ errors.
What could go wrong: This is a completed trial with 108 children, but results may not apply to all speech errors or age groups. Biofeedback may not work for everyone and requires specialized equipment.
