Background: The term progressive apraxia of speech (PAOS) is used to describe speakers presenting with isolated or dominant apraxia of speech in the context of a neurodegenerative syndrome, including primary progressive apraxia of speech (PPAOS) and dominant progressive apraxia of speech (DAOS), respectively. Its motor speech profile has been…

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…

This study evaluated the efficacy of (a) remote video-based behavioral skills training (BST) with added speech outlines on teaching public speaking behaviors and (b) remote video-based awareness training (AT) on speech-disfluency rates. A multiple-baseline design across speech behaviors was used to evaluate the training. Remote video-based BST and…

Purpose: Phonological processing skills, or using phoneme knowledge to process language, in preschool- and kindergarten-age children are an important indicator of children's future reading abilities. However, assessing phonological processing skills can be difficult in children with speech sound disorders because scoring often requires that…

Background: The dialect spoken by children influences diagnostic decision-making regarding the identification and severity of speech sound disorder (SSD). Aims: The primary objective was to review papers that examined the influence of dialect on the identification of SSD in Vietnamese-speaking children. Methods & Procedures: Five studies of…

Background: Approximately 50% of all young children with a developmental language disorder (DLD) also have problems with speech production. Research on speech sound development and clinical diagnostics of speech production difficulties focuses mostly on accuracy; it relates children's phonological realizations to adult models. Contrarily to these…

Background: Perceptual measures such as speech intelligibility are known to be biased, variant and subjective, to which an automatic approach has been seen as a more reliable alternative. On the other hand, automatic approaches tend to lack explainability, an aspect that can prevent the widespread usage of these technologies clinically. Aims: In…

Background and Aim: Recently, there has been a lot of interest surrounding the term gestalt language processor (GLP) which is associated with Natural Language Acquisition (NLA): a protocol intended to support the language development of autistic people. In NLA, delayed echolalia is presumed raw source material that GLPs use to acquire language in…

Motor deficits are a phenotype observed in children with autism. When provided with motor intervention, the children progress across different developmental domains. The problem is teachers in self-contained classrooms for nonverbal children with autism faced obstacles that needed to be overcome in implementing a motor intervention plan in public…

Purpose: The purpose of this study was to examine the nature of speech disfluencies in autistic young adults and controls by using a wide-range disfluency classification of typical disfluencies (TD; i.e., filled pauses, revisions, abandoned utterances, and multisyllable word and phrase repetitions), stuttering-like disfluencies (SLD; i.e., sound…

Background: Children with speech sound disorder (SSD) are at increased risk of reading difficulties due to poor phonological processing skills. However, the extent to which children with SSD demonstrate weaknesses on specific or all phonological processing tasks is not well understood. Aims: To examine the phonological processing abilities of a…

Purpose: Recent work suggests that speech perception is influenced by the somatosensory system and that oral sensorimotor disruption has specific effects on the perception of speech both in infants who have not yet begun to talk and in older children and adults with ample speech production experience; however, we do not know how such disruptions…

Purpose: Phonologically complex targets (e.g., [pl-]) are understood to facilitate widespread gains following speech sound intervention, and yet, available research largely features word-"initial" clusters. The present study investigates intervention effects following treatment of complex clusters presented in word-"final"…

Echolalia can negatively impact multiple skill areas in children diagnosed with autism spectrum disorder (ASD), including skills related to academic and social performance. The purpose of this study was to employ a multiple probe across participants design to evaluate the effects of tact training on delayed echolalia in three children in China…

Background: Unaided communication behaviours may provide communication support for persons with severe cerebrovascular accidents (CVA), as these individuals often experience severe communication difficulties, regardless of the aetiology. Though often subtle, these behaviours are present during all stages of recovery, and therefore communication…
