Purpose: The purpose of this article is to provide trial-by-trial practice performance data in relation to learning (outcome probe data) as collected from 18 treatment sessions provided to children with severe speech sound disorders. The data illustrate the practice-learning paradox: Specific, perfect practice performance is not required for…

Background: Developmental dysarthria is a motor speech impairment commonly characterized by varying levels of reduced speech intelligibility. The relationship between intelligibility deficits and acoustic vowel space among these individuals has long been noted in the literature, with evidence of vowel centralization (e.g., in English and…

Background: Speech and language researchers study phonological acquisition and evaluate the errors that children make to understand this complex process. This information provides clinicians with a scientific reference for better assessment and intervention services to children with articulation/phonological disorders. Urdu is a language spoken by…

Purpose: Earlier investigations based on word and sentence repetition tasks had revealed that the most prevalent metrical pattern in German (the trochee)--unlike the iambic pattern--facilitates articulation in patients with apraxia of speech (AOS; e.g., Aichert, Späth, & Ziegler, 2016), confirming that segmental and prosodic aspects of speech…

Purpose: The aim of this study was to conduct a systematic review and meta-analysis to investigate whether preschool- and early school-age children with speech sound disorders (SSDs) have difficulties with speech perception. Method: Systematic searching of 8 electronic databases identified 73 eligible studies across 71 articles examining the…

Purpose: The purpose of this work was to study how voice use in daily life is impacted by Parkinson's disease (PD), specifically if there is a difference in voice sound level and phonation ratio during everyday activities for individuals with PD and matched healthy controls. A further aim was to study how variations in environmental noise impact…

Purpose: In healthy speakers, the more frequent and probable a word is in its context, the shorter the word tends to be. This study investigated whether these probabilistic effects were similarly sized for speakers with dysarthria of different severities. Method: Fifty-six speakers of New Zealand English (42 speakers with dysarthria and 14 healthy…

Children with autism spectrum disorder (ASD) who have limited speech are often taught to communicate using a speech-generating device (SGD). We evaluated procedures for teaching a mand for information (i.e., "Where" is [item]?) using an interrupted behavior chain procedure. In Experiment 1, all participants (3 children with ASD who…

Background: A total of 68% of pre-school children with cleft palate have speech problems requiring speech therapy. There is a lack of access to regular targeted therapy. Parent training leads to positive outcomes in early communication skills in cleft palate and non-cleft speech disorders. Connected health has been used to address inadequate…

Researchers report that caregiver-implemented communication interventions are effective and feasible. However, limited information is available on training and coaching programs for families who speak languages other than English in their homes. The purpose of this study was to evaluate a parent training and coaching program originally designed to…

Learning academic vocabulary is a crucial task for all students, but especially challenging for students with speech, language, and communication needs (SLCN) and those who are multilingual. Following a participatory research strategy, we analyze whether iconic gestures can be integrated in teaching routines in an inclusive elementary school and…

Purpose: The objective was to determine velopharyngeal (VP) status of stop consonants and vowels produced by young children with repaired cleft palate (CP) and typically developing (TD) children from 12 to 18 months of age. Method: Nasal ram pressure (NRP) was monitored in 9 children (5 boys, 4 girls) with repaired CP with or without cleft lip and…

Purpose: This study sought to investigate the interaction of speech movement execution with higher order lexical parameters. The authors examined how lexical characteristics affect speech output in individuals with Parkinson's disease (PD) and healthy control (HC) speakers. Method: Twenty speakers with PD and 12 healthy speakers read sentences…

Purpose: The clinical diagnosis of motor speech disorders (MSDs) is mainly based on perceptual approaches. However, studies on perceptual classification of MSDs often indicate low classification accuracy. The aim of this study was to determine in a forced-choice dichotomous decision-making task (a) how accuracy of speech-language pathologists…

This study examines interactions between students with atypical motor and speech abilities, their teachers, and eye tracking devices under varying conditions typical of educational settings (e.g., interactional style, teacher familiarity). Twelve children (aged 4-12 years) participated in teacher-guided sessions with eye tracking software that are…
