Purpose: This study investigated phonological and speech motor neural networks in children with residual speech sound disorder (RSSD) during an overt Syllable Repetition Task (SRT). Method: Sixteen children with RSSD with /[voiced alveolar approximant]/ errors (6F [female]; ages 8;0-12;6 [years;months]) and 16 children with typically developing…

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…

Background: Acquired apraxia of speech (AOS) involves speech-production deficits on both the segmental and suprasegmental levels. Recent research has identified a non-linear interaction between the metrical structure of bisyllabic words and word-production accuracy in German speakers with AOS, with trochaic words (strong-weak stress) being…

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…

Without data on speech accuracy of Vietnamese-English speakers, speech-language pathologists (SLPs) are unable to assess accurately this population for speech sound disorders. This study explored the heretofore uninvestigated speech accuracy and use of Vietnamese-English bilingual individuals residing in the USA. Participants included six…

Purpose: The purpose of this study was to examine the diagnostic accuracy of traditional measures of phonological ability developed for monolingual English-speaking children with their bilingual peers in both English and Spanish. We predicted that a composite measure, derived from a combination of English and Spanish phonological measures, would…

Purpose: Bilingual children whose phonological skills are evaluated using measures designed for monolingual English speakers are at risk for misdiagnosis of speech sound disorders (De Lamo White & Jin, 2011). Method: Forty-four children participated in this study: 15 typically developing monolingual English speakers, 7 monolingual English…

Purpose: Children with speech sound disorder (SSD) mispronounce more speech sounds than is typical for their age and a growing body of research suggests that a deficit in speech perception abilities contributes to development of the disorder. However, little work has been done to characterize the neurophysiological processes indexing speech…

Background: Psycholinguistic models of language production provide a framework for determining the locus of language breakdown that leads to speech-sound disorder (SSD) in children. Aims: To examine whether children with SSD differ from their age-matched peers with typical speech and language development (TD) in the ability phonologically 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,…

This study sought to assess the level of correspondence between parent and teacher report of concern about young children's speech and specialist assessment of speech sound disorders (SSD). A sample of 157 children aged 4-5 years was recruited in preschools and long day care centres in Victoria and New South Wales (NSW). SSD was assessed…

Accurate production of polysyllables (words of three or more syllables) can be challenging for children with phonological impairment. Research with typically developing children has suggested that children can improve their polysyllable productions in response to requests for clarification containing an incorrect model of a target word (Gozzard et…

Purpose: This study aimed to compare sound production errors arising due to phonological processing impairment with errors arising due to motor speech impairment. Method: Two speakers with similar clinical profiles who produced similar consonant cluster simplification errors were examined using a repetition task. We compared both overall accuracy…

Many children who neutralize phonemic contrasts in production exhibit diminished perception of the same contrasts. It is usually difficult to determine whether the perception deficit caused the production error, or vice versa; however, the direction of causation has implications for treatment planning. This study examines perception-production…
