Purpose: This study collected measures of auditory-perceptual and oral somatosensory acuity in typically developing children and adolescents aged 9-15 years. We aimed to establish reference data that can be used as a point of comparison for individuals with residual speech sound disorder (RSSD), especially for RSSD affecting American English…

Background: Children born with cleft palate ± lip (CP ± L) are at risk of speech sound disorder (SSD). Up to 40% continue to have SSD at age 5-6 years. These difficulties are typically described as articulatory in nature and often include cleft speech characteristics (CSC) hypothesized to result from structural differences. In non-CP ± L SSD…

Although pragmatic speech impairments have been found across the autism spectrum, how these manifest in minimally verbal (MV) individuals with autism spectrum disorder (ASD) has not been studied. We compared the pragmatic speech profiles of MV (n = 50) and verbally fluent (VF) individuals with ASD (n = 50; 6-21 years-old) based on natural language…

This meta-analysis aimed to evaluate single-case studies that used high-tech speech-generating devices (SGDs) for children with autism spectrum disorders (ASD) ages 0-8. The focus of this review was to measure the effect size of high-tech SGD intervention on verbal behavior. The review included 20 studies with 54 participants with ASD. The results…

Purpose: The current research sought to determine (a) if speech inconsistency is a core feature of childhood apraxia of speech (CAS) or if it is driven by comorbid language impairment that affects a large subset of children with CAS and (b) if speech inconsistency is a sensitive and specific diagnostic marker that can differentiate between CAS and…

The current study was designed to examine the relationships between performance on a nonverbal phoneme deletion task administered in a dynamic assessment format with performance on measures of phoneme deletion, word-level reading, and speech sound production that required verbal responses for school-age children with speech sound disorders (SSDs).…

The purpose of this article is to discuss definitional and measurement issues as well as empirical evidence regarding temperament, especially with regard to children's (a)typical speech and language development. Although all ages are considered, there is a predominant focus on children. Evidence from considerable empirical research lends support…

Auditory processing problems in persons with dyslexia are still subject to debate, and one central issue concerns the specific nature of the deficit. In particular, it is questioned whether the deficit is specific to speech and/or specific to temporal processing. To resolve this issue, a categorical perception identification task was administered…

Purpose: To compare the relative effects of random vs. blocked practice schedules in treatment for childhood apraxia of speech (CAS). Although there have been repeated suggestions in the literature to use random practice in CAS treatment, no systematic studies exist that have directly compared random with blocked practice in this population.…

Purpose: This study was designed to identify and describe between-word simplification patterns in the continuous speech of children with speech sound disorders. It was hypothesized that word combinations would reveal phonological changes that were unobserved with single words, possibly accounting for discrepancies between the intelligibility of…

Aim: To identify the use and utility of language comprehension tests for unintelligible or non-speaking children with severe cerebral palsy (CP). Method: Severe CP was defined as severe dysarthria (unintelligible speech) or anarthria (absence of speech) combined with severe limited mobility, corresponding to Gross Motor Function Classification…

Purpose: This study examined reading performance and morphological awareness development in 2 groups of children with speech impairment who had received differing types of intervention during their preschool years. Method: The children were aged between 7;6 and 9;5 (years;months) at the time of the study. Group 1 (n = 8) had received preschool…

Phonotactic patterns of seven 11-15-year-old Kannada speaking children with Down syndrome (DS), mental age matched children with mental retardation (MR) without DS and six 4-5-year-old typically developing (TD) children were investigated. Conversational speech analyses and target analyses of conversational speech were carried out in all three…

Two experiments examined whether listening to multiple presentations of recorded speech stimuli influences the reliability and accuracy of judgments of children's speech production accuracy. In Experiment 1, 10 listeners phonetically transcribed words produced by children with phonological impairments after a single presentation and after the word…

Evidence of the positive outcomes of phonological treatment is reviewed, with particular emphasis on treatment procedures that have been deemed effective, the specific effects of these treatment on improving intelligibility, and comparisons between treatments in facilitating improved sound production. The effect of phonological disorders on…
