Purpose: This study investigated articulatory patterns for American English /[Voiced alveolar approximant]/ in children with and without a history of residual speech sound disorder (RSSD). It was hypothesized that children without RSSD would favor bunched tongue shapes, similar to American adults reported in previous literature. Based on clinical…

Purpose: The purpose of this study was to examine the perception of correctly and incorrectly produced words in children with and without phonological speech sound disorder (SSD) with similar vocabulary and language skills. Method: Thirty-six monolingual English-speaking children aged 4 and 5 years, half with SSD and half with typical speech and…

Purpose: This study aimed to identify predictors of response to treatment for residual speech sound disorder (RSSD) affecting English rhotics. Progress was tracked during an initial phase of traditional motor-based treatment and a longer phase of treatment incorporating ultrasound biofeedback. Based on previous literature, we focused on baseline…

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…

A word learning paradigm was used to teach children novel words that varied in phonotactic probability and neighborhood density. The effects of frequency and density on speech production were examined when phonetic forms were nonreferential (i.e., when no referent was attached) and when phonetic forms were referential (i.e., when a referent was…

The goal of this study was to investigate the effects of prosodic stress patterns and semantic depth on word learning. Twelve preschool-aged children with typically developing speech and language skills participated in a word learning task. Novel words with either a trochaic or iambic prosodic pattern were embedded in one of two learning…

The purpose of the current study is to document phonological change from a multidimensional perspective for a 3-year-old boy with phonological disorder by comparing three measures: (1) accuracy of consonant productions, (2) dynamic assessment, and (3) acoustic analysis. The methods included collecting a sample of the targets /s, [image omitted],…

This study examined the effect of lexical aspect and phonology on regular past-tense production. Data are presented from a group of 31 children, mean age 33 months, with typical language development. A case study of a 50-month-old child with Specific Language Impairment (SLI) is also presented. Children imitated sentence pairs that included an…
