Treatment of Articulation and Phonological Impairment
Overview
Individuals diagnosed with speech sound disorder (SSD) are a heterogeneous group. As a result, a variety of approaches exist to treat SSD. The diversity among approaches to intervention is a topic of much debate in the speech-language pathology research community. Researchers agree that SSD-focused interventions work and have positive effects (Tyler, 2008). However, there is often minimal evidence to tie intervention approaches to treatment outcomes.
Williams, McLeod, and McCauley (2010) documented 46 distinct approaches to intervention for individuals with SSD. This diversity suggests that multiple approaches are effective solutions to the same problem (Lancaster, et al., 2010). Multiple approaches to intervention provide SLPs with an array of options to individualize treatment, but can also complicate the decision-making process.
Differentiating Factors
A major differentiating factor among intervention approaches is whether the focus is on articulation, phonology, or both. Approaches to intervention of SSD typically concentrate directly on speech (articulation) or directly on language and indirectly on speech (phonology). At times, a combination of both approaches may be incorporated into therapy.
Articulation Approaches to Intervention
Articulatory approaches to intervention target each sound deviation individually when errors are assumed to be motor-based. The overall goal is the correct production of the
