The goals of the present study were to (1) examine the effects of the multiple opposition phonological approach on improving phoneme production accuracy in children with severe phonological disorders and (2) explore whether the multiple opposition approach is feasible for the telepractice service delivery model. A multiple-baseline,…

An adolescent with a persistent frontal lisp participated in a two-part 11-session intervention case study. The first phase used ultrasound imagery and acoustic, phonetic and voice education to provide information about articulatory setting (AS) and general awareness of the speech production process. The second phase used traditional articulation…

Purpose: This study explored relationships among perceptual, ultrasound, and acoustic measurements of children's correct and misarticulated /r/ sounds. Longitudinal data documenting changes across these parameters were collected from 2 children who acquired /r/ over a period of intervention and were compared with data from children with typical…

Background: School-aged children with persisting speech sound disorders (SSDs) may show little improvement in speech accuracy following phonological or articulation therapy. Aims: To determine the effects of establishing consonant production in facilitative vowel contexts for a 7-year-old boy (CD) with persisting post-alveolar fronting. CD had…

Children with unintelligible speech differ in severity, underlying deficit, type of surface error patterns and response to treatment. Detailed treatment case studies, evaluating specific intervention protocols for particular diagnostic groups, can identify best practice for children with speech disorder. Three treatment case studies evaluated the…

Jaw movement patterns were examined longitudinally in a 3-year-old male with childhood apraxia of speech (CAS) and compared with a typically developing control group. The child with CAS was followed for 8 months, until he began accurately and consistently producing the bilabial phonemes /p/, /b/, and /m/. A movement tracking system was used to…

The hypothesis that a language training (vocabulary building) or lexical approach to the remediation of final sound omissions may be an effective method of therapy was tested with a 6-year-old trainable mentally retarded boy. (Author/GW)

This study evaluated whether variations in the structure of minimal versus maximal opposition treatments would result in empirical differences in phonological learning with three four-year-old boys who excluded at least six sounds from their phonetic and phonemic inventories. Results indicated that treatment of maximal oppositions led to greater…

The Lidcombe Program is an operant treatment for early stuttering. Outcomes indicate that the program is effective; however, the underlying mechanisms leading to a successful reduction of stuttering remain unknown. The purpose of this study was to determine whether fluency achieved with the Lidcombe Program was accompanied by concomitant reduction…
