This study examines the displayed communicative competence and agency of a non-speaking student at a compulsory school for children with severe learning disabilities. The use of two different speech-generating devices (a single-message versus a multi-message speech-generating device) and the assignment of participation role (having the role of…

Background: Compensatory cleft speech disorders can severely impact speech understandability and speech acceptability. Speech intervention is necessary to eliminate these disorders. There is, however, currently no consensus on the most effective speech therapy approach to eliminate the different subtypes of compensatory cleft speech disorders.…

This mixed methods retrospective analysis analyzed change using a linguistic-based approach during speech therapy among first or second-grade students with a speech sound disorder. Measures analyzed change within intelligibility, phonemic awareness, decoding, ability to apply skills, and response to IEP goals related to speech. Five schools…

This study compared the different services and types of disorders Oklahoma and Texas K-12 SLP's provided through teletherapy as compared to face-to-face therapy before and during the COVID-19 pandemic. A Google forms survey was available to SLPs from June through October, 2021, assessing three age groups of children: elementary (5-10 years),…

Background: Despite initial underreporting of language dysfunctions in corticobasal syndrome (CBS), aphasia is now recognized as a frequent feature of this disease. Aphasia in CBS seems clinically overlying to a non-fluent/agrammatic primary progressive aphasia (nfaPPA), which is also a clinical phenotype associated with corticobasal degeneration…

Purpose: Robust improvements in intelligibility following familiarization, a listener-targeted perceptual training paradigm, have been revealed for talkers diagnosed with spastic, ataxic, and hypokinetic dysarthria but not for talkers with hyperkinetic dysarthria. While the theoretical explanation for the lack of intelligibility improvement…

Background: Congenital hearing loss is the most common birth anomaly, typically influencing speech and language development, with potential for later academic, social and employment impacts. Yet, surprisingly, the nuances of how speech is affected have not been well examined with regards to the subtypes of speech-sound disorder (SSD). Nor have the…

Background: The relationship between auditory processing (AP) test results and reading has shown significant correlations in the literature; however, whether the relationship is more coincidental or more causal is uncertain. Improving AP deficits is also not well understood, especially regarding its impacts on real-world benefits such as with…

Purpose: Reduced intensity is a hallmark of speech production in Parkinson's disease (PD). Previous work has examined the perception of intensity in PD to explain these speech deficits. This study reports loudness ratings of pure tones by individuals with PD and controls, all with normal thresholds for older adults. Method: Twenty individuals with…

Purpose: Childhood apraxia of speech (CAS) is hypothesized to arise from deficits in speech motor planning and programming, but the influence of abnormal speech perception in CAS on these processes is debated. This study examined speech perception abilities among children with CAS with and without language impairment compared to those with…

Speech disorders occur commonly in individuals with Down syndrome (DS), although data regarding the auditory-perceptual speech features are limited. This descriptive study assessed 47 perceptual speech features during connected speech samples in 26 children with DS. The most severely affected speech features were: naturalness, imprecise…

Purpose: Studies of infants' early vocalizations have proven helpful in describing the developmental characteristics of various communication disorders. However, few studies have addressed the early vocalizations of infants and toddlers who were later diagnosed, as older children, with childhood apraxia of speech (CAS). We refer to these infants…

Purpose: Congenital amusia is an inborn neurogenetic disorder of fine-grained pitch processing. This study attempted to pinpoint the impairment mechanism of speech processing in tonal language speakers with amusia. We designed a series of perception tasks aiming at selectively probing low-level pitch processing and relatively high-level…

The Childhood-Onset Fluency Disorder (stuttering) reflects a marked impairment in speech fluency that is not attributable to stroke or another medical condition, and developmental or mental disorder (Birstein, 2015). This article examines Childhood-Onset Fluency Disorder (Stuttering): An interruption in the flow of speaking. The focus is on the…

Purpose: Cluttering is a fluency disorder that has been noted clinically in individuals with fragile X syndrome (FXS). Yet, cluttering has not been systematically characterized in this population, hindering identification and intervention efforts. This study examined the rates of cluttering in male young adults with FXS using expert clinical…
