New speech therapy approach may help children with cleft palate speak more clearly
NCT ID NCT07692061
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This trial compares two speech therapy approaches for Cantonese-speaking children and teens aged 4 to 17 who have cleft palate with or without cleft lip. One method focuses on practicing individual sounds, while the other targets the overall sound system. The goal is to see which approach better improves speech clarity, acceptability, and everyday communication.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Non-linear phonological speech intervention
- What this could lead to
- If effective, this approach could offer a more efficient speech therapy method for children with cleft palate, improving their speech clarity and social participation.
- What could go wrong
- This is a small early-stage trial with only 12 participants, so results may not apply broadly. The therapy may not outperform existing methods.
