Biofeedback intervention for speech sound disorder


Speech sound disorder in childhood poses a barrier to academic and social participation, with potentially lifelong consequences for educational and occupational outcomes. Particular challenges are faced by children with residual speech errors, or atypical speech patterns that persist past 9 years of age. These errors, which frequently involve sounds like /r/ and /s/, may remain unchanged despite years of therapy.


Recent research suggests that these errors can be eliminated through therapy incorporating visual biofeedback. Biofeedback uses instrumentation to create a real-time representation of some aspect of speech that is difficult to perceive under ordinary circumstances. Different technologies can be used:


• In ultrasound biofeedback therapy, a learner can observe the shape and movements of his/her

  tongue in real time and attempt to match an ultrasound image of a correctly articulated target sound.





 We also use ultrasound to look at other sounds. If you know a younger child who has trouble with the "k" sound (e.g. "tandy" for candy), click here to read about our study investigating this speech pattern!

 • In acoustic biofeedback therapy, learners view a real-time image of the acoustic signal of their speech,

  which they can attempt to match to a model representing correct production of the target sound.




Do you know an NYC-area child who has trouble with the /r/ sound?

If you are a parent/caregiver or clinician/educator in the NYC area who would like to recommend a participant aged 9-14 for enrollment in our study of biofeedback treatment for /r/ errors, click here or read more here.
