Abstract

There is established efficacy for the treatment for apraxia of speech (AOS); however, the number of efficacious treatments is few and each is in need of replication. This single-subject multiple-baseline across-behaviors experimental study assessed the effects of on-line visual kinematic and clinician supplied auditory perceptual feedback on the acquisition, generalization and maintenance of speech production in a person with mild-to-moderate severity AOS. Intervention yielded immediate acquisition of nine sequentially treated behaviors and generalization to numerous untreated targets within and outside of the phoneme classes. Differential acquisition effects were realized for the frequency (50% versus 100%) of feedback administration
