Purpose: Speech motor skill is refined over the course of practice, which is commonly reflected by increased accuracy and consistency. This research examined the relationship between auditory-perceptual ratings of word accuracy and measures of speech motor timing and variability at pre- and posttreatment in children with childhood apraxia of…

Purpose: The purpose of this study is to identify predictors of treatment outcomes in Rapid Syllable Transition Treatment (ReST) for childhood apraxia of speech through an individual participant data meta-analysis. Method: A systematic literature search identified nine ReST studies for inclusion. Individual participant data were obtained, and…

Purpose: Childhood apraxia of speech (CAS) is a multivariate motor speech disorder that requires a motor-based intervention approach. There is limited treatment research on young children with CAS, reflecting a critical gap in the literature given that features of CAS are often in full expression early in development. Dynamic Temporal and Tactile…

Background: Individuals with developmental dysarthria typically demonstrate reduced functioning of one or more of the speech subsystems, which negatively impacts speech intelligibility and communication within social contexts. A few treatment approaches are available for improving speech production and intelligibility among individuals with…

Purpose: This study evaluated whether outcomes from treatment, which includes ultrasound visual feedback (UVF), would be more or less effective when combined with auditory perception training for children with residual /[voiced alveolar approximant]/ errors. Method: Children ages 8-16 years with /[voiced alveolar approximant]/ distortions…

Purpose: This study examined how lexical representations and intervention intensity affect phonological acquisition and generalization in children with speech sound disorders. Method: Using a single-subject multiple baseline design, 24 children with speech sound disorders (3;6 to 6;10 [years;months]) were split into 3 word lexicality types…

Background & Aims: Even though evidence for the use of linguistic-phonological intervention approaches in children with a cleft (lip and) palate (CP±L) is still limited, these approaches are being used by speech-language pathologists (SLPs) to treat active or compensatory cleft speech disorders in clinical practice. It is, however, unknown to…

Purpose: This study aimed to identify predictors of response to treatment for residual speech sound disorder (RSSD) affecting English rhotics. Progress was tracked during an initial phase of traditional motor-based treatment and a longer phase of treatment incorporating ultrasound biofeedback. Based on previous literature, we focused on baseline…

Background: Individuals with intellectual disability (ID) often demonstrate speech impairments and reduced intelligibility. However, traditional treatment methods, which involve using repetitive verbal and non-verbal exercises, may not be fully suitable for this population. As adults with ID tend to lose interest and motivation facing the demands…

Purpose: This retrospective study was intended to replicate findings from Sacks et al. (2013) regarding the efficacy of using the SATPAC (Systematic Articulation Training Program Accessing Computers) approach for remediating speech sound errors in a Tier 3 response to intervention (RTI) context. Method: Nine children aged 7;7 (years;months) to…

The goals of the present study were to (1) examine the effects of the multiple opposition phonological approach on improving phoneme production accuracy in children with severe phonological disorders and (2) explore whether the multiple opposition approach is feasible for the telepractice service delivery model. A multiple-baseline,…

Purpose: This randomized controlled trial compared the experimental Rapid Syllable Transition (ReST) treatment to the Nuffield Dyspraxia Programme-Third Edition (NDP3; Williams & Stephens, 2004), used widely in clinical practice in Australia and the United Kingdom. Both programs aim to improve speech motor planning/programming for children…

Purpose: The authors designed this investigation to extend the development of a treatment for acquired apraxia of speech (AOS)--sound production treatment (SPT)--by examining the effects of 2 treatment intensities and 2 schedules of practice. Method: The authors used a multiple baseline design across participants and behaviors with 4 speakers with…

Purpose: Misarticulation of /r/ is among the most challenging developmental speech errors to remediate. Case studies suggest that visual biofeedback treatment can establish perceptually accurate /r/ in clients who have not responded to traditional treatments. This investigation studied the response of children with persistent /r/ misarticulation…

Purpose: This investigation was designed to elucidate the effects of repeated practice treatment on sound production accuracy in individuals with apraxia of speech (AOS) and aphasia. A secondary purpose was to determine if the addition of rate/rhythm control to treatment provided further benefits beyond those achieved with repeated practice.…
