Purpose: Earlier work has established developmental benchmarks for intelligibility and articulation rate, but the intersection of these two variables, especially within individual children, has received limited attention. This study examines the interaction between intelligibility and speaking rate in typically developing children between the ages…

In this study, temporal speech cues were integrated into online curriculum to solve non-routine problems in curricular multimedia. Teachers-in-training (n=56) were randomly assigned to one of three treatment conditions. It was expected that participants in the temporal speech cues condition would be more likely to solve problems than those in the…

Purpose: Here, we examine the possibility that memory consolidation during a period of postpractice rest or nocturnal sleep can bolster speech motor learning in the absence of additional practice or effort. Method: Using web-administered experiments, 74 typical, American English talkers trained in a nonnative vowel contrast then had a 12-hr delay…

Purpose: Apraxia of speech (AOS) is a motor speech disorder affecting articulatory planning and speech programming. When AOS is the sole manifestation of neurodegeneration, it is termed primary progressive apraxia of speech (PPAOS). Recent work has shown that there are distinct PPAOS subtypes: phonetic, prosodic, and those that do not clearly…

Purpose: One of the strategies that can be used to support speech communication in deaf children is cued speech, a visual code in which manual gestures are used as additional phonological information to supplement the acoustic and labial speech information. Cued speech has been shown to improve speech perception and phonological skills. This…

The first purpose of the present study was to characterize progressive and metacognitive dialogue in knowledge-building classrooms. The second purpose was to examine the association between the quality of classroom dialogue and students' learning outcomes, including domain knowledge and conception of collaboration. One hundred thirty college…

The study aimed to analyse the production of plosive sounds by trilingual speakers of L1 Polish - L2 English - L3 Norwegian. The main objective was to trace any changes in the VOT production of fortis and lenis stops in all three languages (Polish, English and Norwegian) produced by novice L3 learners with a focus on possible cross-linguistic…

Background: Developmental Language Disorder (DLD) impacts various aspects of children's language abilities, including the processing of inflectional morphology. Prior research suggests that children with DLD exhibit deficits in processing speed and sensitivity to grammatical inflections, yet the relationship between these deficits remains unclear.…

Background: Dementia is a cognitive decline that leads to the progressive deterioration of an individual's ability to perform daily activities independently. As a result, a considerable amount of time and resources are spent on caretaking. Early detection of dementia can significantly reduce the effort and resources needed for caretaking. Aims:…

Background: Ultrasound visual biofeedback (UVBF) has the potential to be useful for the treatment of compensatory errors in speakers with cleft palate ± lip (CP±L), but there is little research on its effectiveness, or on how acceptable families find the technique. This study reports on parents' and children's perspectives on taking part in a…

Speech perception research has commonly relied on untrained listeners to provide impressionistic judgments of second language (L2) speech, and training listeners has been rare. The current study therefore explores the implications of training novice listeners (NLs) to rate accented speech. A total of 60 listeners were recruited, 30 who remained…

Substantial evidence exists suggesting that access to articulatory gestures during instruction improves students' phonological awareness skills, but researchers have yet to explore the role of articulatory gestures in initial phonics instruction. The purpose of this study was to examine if visual access to articulatory gestures (i.e., mouth cues)…

Purpose: The aim of this study was to explore relations between speech sound disorder severity and selective mutism in a group of children with 7q11.23 duplication syndrome (Dup7), a genetic condition predisposing children to childhood apraxia of speech (CAS) and other speech sound disorders and to anxiety disorders, including selective mutism and…

Purpose: This meta-analysis study aimed to determine the optimal level of talker variability in training to maximize second-language speech learning. Method: We conducted a systematic search for studies comparing different levels of talker variability in nonnative speech training, published through July 2024. Two independent reviewers screened…

This case report describes a young child with inconsistent phonological disorder (IPD). The child presented with unintelligible speech. She made limited progress on individual speech production goals targeting phonological patterns over 4 years, remaining unintelligible. The child was diagnosed with IPD following an inconsistency assessment and…
