Purpose: The aim of this study was to examine how nonword repetition (NWR) performance may be impacted by the presence of concomitant speech and language disorders in young children who stutter (CWS). Method: One hundred forty-one children (88 CWS and 53 children who do not stutter [CWNS]) participated. CWS were divided into groups based on the presence of speech sound and/or language disorder or typical speech sound production and language abilities. NWR abilities were measured using stimuli composed of one- to four-syllable nonwords. Results: CWS with typical speech and language and CWNS had higher accuracy scores than CWS with concomitant speech and language disorders. We found no difference in accuracy scores between CWNS and CWS with typical speech and language abilities, nor did we find differences between CWS with speech sound disorder and CWS with both speech sound and language disorders. Accuracy decreased as nonword length increased for all groups. Conclusions: We found that the presence of a concomitant speech and language disorder was a driving factor behind poorer NWR performance in CWS. Accuracy scores differentiated CWS with concomitant disorders from CWS with typical speech and language but not CWS with typical speech and language from CWNS. Considering the speech and language abilities of CWS helped clarify poorer NWR performance and enhances generalizability to the population that exists clinically.

Purpose A growing body of research suggests that a deficit in speech perception abilities contributes to the development of speech sound disorder (SSD). However, little work has been done to characterize the neurophysiological processes indexing speech perception deficits in this population. The primary aim of this study was to compare the neural activity underlying speech perception in young children with SSD and with typical development (TD). Method Twenty-eight children ages 4;1–6;0 (years;months) participated in this study. Event-related potentials (ERPs) were recorded while children completed a speech perception task that included phonetic (speech sound) and lexical (meaning) matches and mismatches. Groups were compared on their judgment accuracy for matches and mismatches as well as the mean amplitude of the phonological mapping negativity (PMN) and N400 ERP components. Results Children with SSD demonstrated lower judgment accuracy across the phonetic and lexical conditions compared to peers with TD. The ERPs elicited by lexical matches and mismatches did not distinguish the groups. However, in the phonetic condition, the SSD group exhibited a more consistent left-lateralized PMN effect and a delayed N400 effect over frontal sites compared to the TD group. Conclusions These findings provide some of the first evidence of a delay in the neurophysiological processing of phonological information for young children with SSD compared to their peers with TD. This delay was not present for the processing of lexical information, indicating a unique difference between children with SSD and with TD related to speech perception of phonetic errors.

Abstract Background Speech sound disorder is a communication disorder in which children have persistent difficulty saying words or sounds correctly. It refers to any difficulty or combination of difficulties with perception, motor production, or phonological representation of speech sounds and speech segments. Aim of the Work to construct an Arabic auditory bombardment therapy program and measure its effectiveness in treatment of functional speech sound disorder. Subjects and Methods This study was applied on 60 participants divided into 2 groups (30 for each group) with age ranging from 3-5 years diagnosed with functional speech sound disorder with or without language disorders, attending at the Phoniatrics outpatient clinic in Ain Shams University Hospitals. The test for identification of phonological processes was applied on 60 patients with speech sound disorder selected to participate in this study. These were divided in to 2 groups (Group (1) received only the conventional therapy while group (2) received auditory bombardment in addition to the conventional therapy for 3 months) and the test was repeated again after therapy. Results Group (2) showed high significant difference (improvement) in consonant assimilation, voicing change, final consonant deletion, palatal fronting, gliding, lateralization and glottal replacement while group (1) showed high significant difference (improvement) in syllable deletion and partial cluster reduction. Conclusion The present study showed that application of auditory bombardment therapy program in addition to conventional therapy has high significant improvement than conventional therapy alone.

Background: Pre-school children with co-occurring phonological speech sound disorder and expressive language difficulties are more likely to have ongoing communication and literacy needs compared to children with these difficulties in isolation. However, to date there has been no systematic or scoping review of the literature specific to interventions for this frequently seen and high-risk group. Aims: The objective of this paper is to provide a rigorous and detailed protocol for a scoping review of interventions, which target both phonological speech sound disorder and expressive language difficulties in pre-school children with primary speech, language and communication needs. The protocol includes details on the development of a search strategy, as well as the trial of an extraction tool. Methods/Design: Included studies must aim to concurrently improve both speech production and expressive language. Children within included studies must be aged between 2:0 and 5:11 years and have communication needs with no known cause. In accordance with the Joanna Briggs institute scoping review methods guidelines, an initial search of the Ovid Emcare and Ovid Medline databases was conducted. Following this a final search strategy for these databases were produced. A draft extraction form was developed by the first author; this was then trialed by two authors on four articles each. Discussion: Following the systematic development of an initial search strategy and extraction form, a scoping review of this topic can take place. The development of a rigorous scoping review protocol is essential in enhancing the transparency and reliability of the subsequent review. A pre-developed search strategy and trialing of an extraction form is a fundamental part of this process.

Purpose Generalizations can be made about the order in which speech sounds are added to a child's phonemic inventory and the ways that child speech deviates from adult targets in a given language. Developmental and disordered speech patterns are presumed to reflect differences in both phonological knowledge and skilled motor control, but the relative contribution of motor control remains unknown. The ability to differentially control anterior versus posterior regions of the tongue increases with age, and thus, complexity of tongue shapes is believed to reflect an individual's capacity for skilled motor control of speech structures. Method The current study explored the relationship between tongue complexity and phonemic development in children (ages 4–6 years) with and without speech sound disorder producing various phonemes. Using established metrics of tongue complexity derived from ultrasound images, we tested whether tongue complexity incrementally increased with age in typical development, whether tongue complexity differed between children with and without speech sound disorder, and whether tongue complexity differed based on perceptually rated accuracy (correct vs. incorrect) for late-developing phonemes in both diagnostic groups. Results Contrary to hypothesis, age was not significantly associated with tongue complexity in our typical child sample, with the exception of one association between age and complexity of /t/ for one measure. Phoneme was a significant predictor of tongue complexity, and typically developing children had more complex tongue shapes for /ɹ/ than children with speech sound disorder. Those /ɹ/ tokens that were rated as perceptually correct had higher tongue complexity than the incorrect tokens, independent of diagnostic classification. Conclusions Quantification of tongue complexity can provide a window into articulatory patterns characterizing children's speech development, including differences that are perceptually covert. With the increasing availability of ultrasound imaging, these measures could help identify individuals with a prominent motor component to their speech sound disorder and could help match those individuals with a corresponding motor-based treatment approach.
