Remediating mispronounced /r/ with ultrasound feedback.
What is it about?
Mispronouncing /r/ is a problem for many children, but using ultrasound feedback--allowing the speakers to see their own tongues--is an effective treatment. Here, we found that the amount of feedback given makes a difference. As with other motor learning tests, giving a lot of feedback early and then giving less feedback later was more effective than having low and then high rates of feedback; both were effective, making this technique ever more promising.
Why is it important?
Treatment of /r/ is one of the most frequent tasks for speech-language pathologists, and using ultrasound feedback can greatly improve outcomes.
