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…

Purpose: This study compared the interrater reliability of adult naïve listeners' perceptual assessments of different speech variables in children with a cleft palate with or without a cleft lip (CP ± L). In addition, the study investigated whether the listeners were able to perceive differences in these speech variables before and after speech…

Background: Recent evidence suggests that speech substantially changes in ageing. As a complex neurophysiological process, it can accurately reflect changes in the motor and cognitive systems underpinning human speech. Since healthy ageing is not always easily discriminable from early stages of dementia based on cognitive and behavioural…

Purpose: The current standard for clinical diagnosis of childhood apraxia of speech (CAS) is expert clinician judgment. The psychometric properties of this standard are not well understood; however, they are important for improving clinical diagnosis. The purpose of this study is to determine the extent to which experts agree on the clinical…

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…

This study compares the use of reporting speech devices (RS) in narrative retells by Spanish-speaking children with (and without) Developmental Language Disorder (DLD). We assessed 50 7-year-old children (25 with DLD and 25 with TD) and analyzed the narrative retells' length and the RS forms introduced by children. In addition, we considered the…

Background: Speech sound disorders (SSDs) are the most common form of communication disorders in children. SSD have an impact on children's abilities to make themselves understood to their listeners and can influence a child's social and emotional well-being as well as their academic achievements. Therefore, it is important to identify children…

Background: Atypical speech prosody has been commonly found among autistic children. Yet it remains unknown whether prosody impairment originates from poor pitch ability in general or whether it is the result of the difficulty in understanding and using prosody for communicative purposes. Aims: To investigate whether native Mandarin…

Background: Phonetic transcription of disordered speech samples is especially crucial for the assessment and treatment of functional or organic speech-sound disorders. Previous studies show that students who struggle with the identification and segmentation of speech sounds are more likely to encounter difficulties with clinical phonetic…

Purpose: In our earlier study, we found that overall accuracy on nonword repetition (NWR) lacked the specificity to differentiate among groups of children who stutter (CWS) with and without concomitant speech sound and/or language disorders and children who do not stutter (CWNS). The aim of this study was to determine whether NWR error…

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…

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…
