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.

Perceptual Assessment

Purpose Speech perception requires individuals to hear and differentiate acoustic signals integral to effective communication. Measuring speech perception in children is challenging because speech perception methodology typically requires lengthy experiments that may fatigue children, resulting in limited knowledge of developmental perceptual skills. In this study, we used an adaptive tracking measure along with a wide range of acoustic stimuli to explore how adults, typically developing (TD) children, and children with speech sound disorder (SSD) perceive small acoustic differences in synthetic speech stimuli. Method Twenty-four adults, 15 TD children, and 15 children with SSD between the ages of 7;0–14;0 (years;months) were administered a newly developed perceptual assessment, the Wide-Range Acoustic Accuracy Scale, to determine the just-noticeable difference in discrimination for three separate syllable contrasts. Each syllable contrast varied along a single acoustic parameter: formant transition duration for /bɑ/–/wɑ/, F3 onset frequency for /dɑ/–/ɡɑ/, and F3–F2 distance for /rɑ/–/wɑ/. Results Findings revealed that adults and TD children did not differ in their discrimination of any syllable contrast, but adults significantly differed from SSD children on all syllable contrasts. TD children and children with SSD differed only on the /rɑ/–/wɑ/ contrast. Conclusions Children with SSD demonstrate less accurate and more variable perception skills relative to adults and TD children for /bɑ/–/wɑ/, /dɑ/–/ɡɑ/, and /rɑ/–/wɑ/ syllable contrasts. Clinical implications of the utility of the Wide-Range Acoustic Accuracy Scale are discussed.

Production Accuracy

Purpose This study compared perception of consonants in medial position by preschoolers, with and without speech sound disorder (SSD), with similar vocabulary and language skills. In addition, we investigated the association between speech perception and production skills. Method Participants were 36 monolingual English-speaking children with similar vocabulary and language skills, half with SSD and half with typical speech and language development (TD). Participants completed a speech perception task targeting phonemes /p, k, s, ɹ/ in /aCa/ disyllables and a comprehensive battery of speech and language measures. Results Children with SSD were significantly less accurate in perceiving speech sound distinctions relative to peers with TD. The phoneme /p/ was perceived significantly more accurately than the three other target phonemes. The correlation between overall perceptual accuracy and overall production accuracy was significant. Furthermore, perceptual accuracy of targets /k, s, ɹ/ was significantly correlated with production accuracy of these phonemes. Conclusions Many children with SSD have greater difficulty perceiving the specific speech sounds they misarticulate. Nonetheless, most children with SSD present with broader perceptual difficulties than peers with TD with similar vocabulary and language skills.

Purpose The purpose of this study was to determine the extent to which school-age children with speech sound disorder (SSD) exhibit concomitant reading difficulties and examine the extent to which phonological processing and speech production abilities are associated with increased likelihood of reading risks. Method Data were obtained from 120 kindergarten, first-grade, and second-grade children who were in receipt of school-based speech therapy services. Children were categorized as being “at risk” for reading difficulties if standardized scores on a word decoding measure were 1 SD or more from the mean. The selected predictors of reading risk included children's rapid automatized naming ability, phonological awareness (PA), and accuracy of speech sound production. Results Descriptive results indicated that just over 25% of children receiving school-based speech therapy for an SSD exhibited concomitant deficits in word decoding and that those exhibiting risk at the beginning of the school year were likely to continue to be at risk at the end of the school year. Results from a hierarchical logistic regression suggested that, after accounting for children's age, general language abilities, and socioeconomic status, both PA and speech sound production abilities were significantly associated with the likelihood of being classified as at risk. Conclusions School-age children with SSD are at increased risk for reading difficulties that are likely to persist throughout an academic year. The severity of phonological deficits, reflected by PA and speech output, may be important indicators of subsequent reading problems.

Homework Completion

Purpose This study investigated the extent to which speech-language pathologists (SLPs) facilitate parents' completion of homework activities for children with speech sound disorder (SSD). In addition, this study explored factors related to more consistent communication about homework completion and strategies considered particularly effective for supporting this element of parental involvement. Method Licensed SLPs serving at least one child with SSD were invited to participate in an online survey. Questions relevant to this study gathered information regarding (a) frequency of communication about homework distribution and follow-up, (b) demographic and workplace characteristics, and (c) an open-ended question about the specific strategies used to support parental involvement and completion of homework activities. Results Descriptive results indicated considerable variability with respect to how frequently SLPs engaged in communication about homework completion, but that school-based SLPs were significantly less likely to engage in this type of follow-up. Strategies considered effective, however, were similar across therapy contexts. Conclusion These results suggest potentially important differences between school-based services and therapy in other contexts with respect to this particular aspect of service provision for children with SSD.
