Tech vs. talk: can screens help kids conquer a common speech hurdle?

This study tested whether adding high-tech visual feedback tools to speech therapy helps children aged 9-15 correct a common, persistent speech sound error (like saying 'wabbit' for 'rabbit') better than traditional therapy alone. Researchers compared two types of visual feedback—one using sound waves and one using ultrasound images of the tongue—against standard methods. The goal was to find more effective treatments for kids who haven't improved with previous help.
