The use of visual biofeedback in the treatment of individuals who have Residual Phonological Errors is discussed. This type of treatment was used with clients who had not improved through traditional auditory/production based treatments. Biofeedback is conceptualized as a cognitive treatment that requires the client's analysis of visual information. The information is used in developing correct productions of Residual Phonological Errors. The reported results indicate that visual feedback is a viable alternative treatment for those who have been unable to develop correct sound production through traditional methods.
Treatment using electropalatography (EPG) is described. Speech learners wear a custom-made appliance called a pseudopalate in order to view their tongue-to-palate (lingual palatal) contacts on a computer monitor. The results from studies with children who have either articulation or phonology-based problems are discussed. Assessments of contact patterns used by articulation-impaired children suggests that they may produce more atypical articulatory contacts than are noted perceptually. Remediation, using electropalatography, showed that the children benefited from learning new articulatory gestures rather than learning to correct isolated errors. Studies with phonologically-impaired children have shown that perceptually neutralized (or non-contrasted) sounds may actually be produced with consistent articulatory contrasts. This knowledge could assist in identifying sounds that might soon emerge and be more responsive to therapy. Training studies with phonologically-impaired children have shown that a motor approach using sound contrasts to teach a phonetic inventory is an effective way to assist these children. Considerations for candidacy for EPG training are also discussed.
Some individuals are unable to achieve correct production of the /r/ phoneme after receiving substantial amounts of treatment. Clark, Schwarz, and Blakeley (1993) developed a removable speech appliance that positions the tongue to produce the /r/ phoneme. Their results indicate that the appliance was successful with a large group of clients. The rationale and issues related to the use of speech appliances are discussed.
