Purpose: This purpose of this study was to assess the frequency and types of phonological process errors in patients with velopharyngeal dysfunction (VPD) and the different types of palatal anomalies. Method: A total of 808 nonsyndromic patients with VPD, who underwent follow-up at the Center for Cleft Palate and Craniofacial Anomalies, from 2000…

Purpose: We sought to provide valid and reliable data on the acquisition of consonant sounds in speakers of Brazilian Portuguese. Method: The sample comprised 733 typically developing monolingual speakers of Brazilian Portuguese (ages 3;0-8;11 [years;months]). The presence of surface speech error patterns, the revised percentage consonants…

The study analysed spectral and tongue shape dynamics of voiceless alveolar and postalveolar fricatives produced by ten children learning Scottish English. Synchronised ultrasound tongue imaging data and acoustic data were used to characterise children's productions of the phonemic contrast. Six children had consistently accurate productions of…

Background: Disruptions of reading processes due to text substitutions can measure how readers use lexical information. Methods: With eye-movement recording, children and adults viewed sentences with either identical, orthographically similar, homophonic or unrelated substitutions of the first characters in target words. To the extent that readers…

This study examined accuracy on syllable-final (coda) consonants in newly-learned English-like nonwords to determine whether school-aged bilingual children may be more vulnerable to making errors on English-only codas than their monolingual, English-speaking peers, even at a stage in development when phonological accuracy in productions of…

The kinds of errors that children and adolescents make on phonological processing tasks were studied with a large sample between ages 4 and 19 (N = 3,842) who were tested on the Kaufman Test of Educational Achievement-Third Edition (KTEA-3). Principal component analysis identified two phonological processing factors: Basic Phonological Awareness…

Purpose: This study examined individual differences in English language learners' (ELLs) nonword repetition (NWR) accuracy, focusing on the effects of age, English vocabulary size, length of exposure to English, and first-language (L1) phonology. Method: Participants were 75 typically developing ELLs (mean age 5;8 [years;months]) whose exposure to…

In early word productions, the same types of errors are manifest in children with cochlear implants (CI) as in their normally hearing (NH) peers with respect to consonant clusters. However, the incidence of those types and their longitudinal development have not been examined or quantified in the literature thus far. Furthermore, studies on the…

The purpose of this study was to explore the nature of spelling errors made by children with dyslexia in Bosnian language with transparent orthography. Three main error categories were distinguished: phonological, orthographic, and grammatical errors. An analysis of error type showed 86% of phonological errors, 10% of orthographic errors, and 4%…

Background: Swahili is widely spoken in East Africa, but to date there are no culturally and linguistically appropriate materials available for speech-language therapists working in the region. The challenges are further exacerbated by the limited research available on the typical acquisition of Swahili phonology. Aim: To describe the speech…

In this study we propose a classification system for spelling errors and determine the most common spelling difficulties of Greek children with and without dyslexia. Spelling skills of 542 children from the general population and 44 children with dyslexia, Grades 3-4 and 7, were assessed with a dictated common word list and age-appropriate…

This study investigated whether Foygel and Dell's (2000) interactive two-step model of speech production could simulate the number and type of errors made in picture-naming by 68 children of elementary-school age. Results showed that the model provided a satisfactory simulation of the mean error profile of children aged five, six, seven, eight and…

Background: Children who are bilingual and have speech sound disorder are likely to be under-referred, possibly due to confusion about typical speech acquisition in bilingual children. Aims: To investigate what is known about the impact of bilingualism on children's acquisition of speech in English to facilitate the identification and treatment of…

Purpose: A mixed-methods approach, evaluating triple word-form theory, was used to describe linguistic patterns of misspellings. Method: Spelling errors were taken from narrative and expository writing samples provided by 888 typically developing students in Grades 1-9. Errors were coded by category (phonological, orthographic, and morphological)…
