Biofeedback in the form of the visual display from the monitor of a real-time spectrograph was presented to a 10-year-old boy and a 14-year-old girl who had been unable to attain correct production of /r/ despite years of treatment. Both perceptual ratings and acoustic measures were made of the clients' productions of /r/ before and after treatment with the spectrograph. The results indicated that children and adolescents can use this type feedback to attain correct production of /r/ when other methods have failed. Potential reasons for the success of this approach are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
