The Efficacy of Ultrasound Biofeedback in Young Children with Hearing Loss
MetadataShow full item record
This study investigated the efficacy of ultrasound biofeedback as an intervention tool for treating speech sound disorders in young children with hearing loss. Two young female children with bilateral cochlear implants participated. They demonstrated persistent errors including velar fronting, stopping, and gliding. Using a single-subject multiple baseline across behaviors design, this study aimed to remediate persisting errors by utilizing ultrasound biofeedback as a real-time visual of lingual movement to assist in the correct production of the phonemes /k/, /g/, /t/, /l/, and /s/ within words. Findings suggest that ultrasound biofeedback may be effective in eliciting accurate production of velar and alveolar consonants in young children with hearing loss.
