Purpose: Although mobile apps are used extensively by speech-language pathologists, evidence for app-based treatments remains limited in quantity and quality. This study investigated the efficacy of app-based visual-acoustic biofeedback relative to nonbiofeedback treatment using a single-case randomization design. Because of COVID-19, all…

Purpose: Children with speech sound disorders have more difficulties producing speech sounds accurately than same-age peers. In addition, they often have difficulties with speech perception, and weaker phonological awareness skills than their peers and are at risk for negative long-term academic and socio-emotional outcomes. In this tutorial, we…

Purpose: The aim of this study was to explore how the frequency with which ultrasound visual feedback (UVF) is provided during speech therapy affects speech sound learning. Method: Twelve children with residual speech errors affecting [alveolar approximant] participated in a multiple-baseline across-subjects design with 2 treatment conditions. One…

This survey addressed a twofold need: first, research into speech sound productions in children with visual impairments and, second, evidence upon which speech-language pathologists might base interventions for children with visual impairments. Fifteen speech-language pathologists responded to a survey about speech sound productions in caseload…

Purpose: This study documented the efficacy of visual-acoustic biofeedback intervention for residual rhotic errors, relative to a comparison condition involving traditional articulatory treatment. All participants received both treatments in a single-subject experimental design featuring alternating treatments with blocked randomization of…

This study explored the feasibility of training school teaching assistants to provide the treatment, Dynamic Temporal and Tactile Cueing to treat childhood apraxia of speech (CAS, also known as developmental verbal dyspraxia). The study used a single case experimental design across behaviours and a qualitative evaluation of teaching assistant…

Background: Children with speech sound disorders (SSD) form a heterogeneous group who differ in terms of the severity of their condition, underlying cause, speech errors, involvement of other aspects of the linguistic system and treatment response. To date there is no universal and agreed-upon classification system. Instead, a number of…

This paper describes a matrix for clinical use in the selection of phonological treatment targets to induce generalization, and in the identification of probe sounds to monitor during the course of intervention. The matrix appeals to a set of factors that have been shown to promote phonological generalization in the research literature, including…

This article describes the case of a client who displayed some interesting patterns of realization of the target English phoneme /r/. These varied according to both distribution within the word, and style of utterance. We speculate as to the cause of some of these forms, and on possible therapy strategies.

This response to Fey (EC 604 058) presents arguments and examples in support of using concepts of phonological processes and constructs in assessing and treating phonological disorders in children. The paper disagrees with Fey's contention that using the term "process" for "rule" leads to confusion. (Author/DB)

Changes in consonant and syllable-level error patterns of three children diagnosed with childhood apraxia of speech (CAS) were investigated in a 3-year longitudinal study. Spontaneous speech samples were analyzed to assess the accuracy of consonants and syllables. Consonant accuracy was low overall, with most frequent errors on middle- and…

Articles on communication and language disorder are presented. All but one are in French; the other is in German. They include: "Specificity of Developmental Dysphasia: Implications for Intervention" (Marc Montfort, Adoracion Juarez Sanchez); "Difficulties with Language Development and Discursive Capacity" (Genevieve de Weck); "Language Production…
