An Integrated Multimodal Intervention Approach to Support Speech and Language Development in Children With Severe Speech Impairments

Abstract

Augmentative and alternative communication (AAC) is often viewed as a "last resort" for children with severe speech sound impairments, with AAC consideration only occurring after years of failed traditional speech therapy. Two main reasons this occurs is because (a) parents view AAC as "giving up" on speech, and (b) parents and speech-language pathologists (SLPs) often believe that implementing AAC will negatively affect natural speech development. These views have consequently led SLPs to dichotomize intervention for these children; either work on natural speech or implement AAC. Recent research has suggested this may not have to be a choice SLPs have to make. This study's purpose was to examine the effects of an integrated multimodal intervention designed to increase the quantity and quality of natural speech production in children who are multimodal communicators due to severe speech sound impairment. A hybrid research design was used to determine the treatment's effectiveness, including single-subject design methodology and qualitative methodology. Three children served as participants, with each child participating in a series of baseline and intervention sessions. The data obtained from the participants suggested the intervention had positive effects on their speech production abilities. Theoretical and clinical implications of these findings are discussed.
