A distinctive-features approach to the remediation of voicing errors produced by hearing-impaired adults

An articulation training procedure based on the clinical extension of distinctive-feature theory was used in an attempt to correct selected voicing errors exhibited by eight hearing-impaired adults. The results indicate that the production of the [+ voice] feature was mastered by all subjects in the phonetic context where it was trained, but generalization of the [+ voice] feature-usage rule was not achieved by the subjects. The findings are discussed relative to the use of feature-training procedures with hearing-impaired adults.
