How does our voice change as we age? (Rojas et al., 2020)

Sandra Rojas, Elaina Kefalianos & ADAM VOGEL
Purpose: Approximately 30% of adults over the age of 50 years present with altered vocal function. Our understanding of how these changes manifest acoustically and perceptually is derived from relatively modest-sized studies using a diversity of tools. Voice changes can arise from the onset of disease or disorder, but also age-related physiological changes, which may not reflect pathology as such. Here, we bring together data on acoustic, perceptual, and instrumental assessments (electroglottography), with the aim...

Speech fluency in apraxia of speech (Harmon et al., 2019)

Tyson G. Harmon, Adam Jacks & Katarina L. Haley
Purpose: Slowed speech and interruptions to the flow of connected speech are common in aphasia. These features are also observed during dual-task performance for neurotypical adults. The purposes of this study were to determine (a) whether indices of fluency related to cognitive–linguistic versus motor processing would differ between speakers with aphasia plus apraxia of speech (AOS) and speakers with aphasia only and (b) whether cognitive load reduces fluency in speakers with aphasia with and without...

Model estimates and model comparisons (Boerma et al., 2017)

Tessel Boerma, Frank Wijnen, Paul Leseman & Elma Blom
"Purpose: Grammatical morphology is often a locus of difficulty for both children with language impairment (LI) and bilingual children. In contrast to previous research that mainly focused on verbal tense and agreement markings, the present study investigated whether plural and past participle formation can disentangle the effects of LI and bilingualism and, in addition, can point to weaknesses of LI that hold across monolingual and bilingual contexts. Method: Monolingual and bilingual children with and without...

Purpose: The study examines the extent of convergence of semantic category members in Spanish–English bilingual children with reference to adults using a semantic fluency task.Method: Thirty-seven children with developmental language disorder (DLD), matched pairwise with 37 typically developing (TD) children in the age range of 7;0–9;11 (years;months), produced items in 7 semantic categories (3 taxonomic and 4 slot-filler) in both Spanish and English. The 10 most frequently produced items for each category by 20 Spanish–English...

Survey of clinicians with specialization in CAS (Randazzo, 2019)

Melissa Randazzo
Purpose: Little is known about how clinicians develop expertise in childhood apraxia of speech (CAS), a rare speech disorder with heterogeneous presentation. The purpose of this survey study was to examine the beliefs and practices of clinicians specializing in CAS.Method: Speech-language pathologists who self-identify as having expertise in CAS (n = 165) completed an online survey regarding influences on clinical practice and beliefs about CAS. Practice patterns and perspectives regarding CAS were analyzed for respondents...

Gender differences (Bradford Wainwright, 2019)

Angela Bradford Wainwright
Purpose: The narrative is an important component of cognitive–linguistic assessment of nonmainstream populations and provides a valuable basis on which to conduct crossethnic/cultural comparisons. Given that there is limited information on the narrative characteristics of African American adults, this study was designed to describe the nature of narrative productions among African American men and women and to determine if gender differences exist in those productions.Method: Seventy-six African American adults—40 women (ages 46–86 years) and 36...

Poor speech perception is not a CAS core deficit (Zuk et al., 2018)

Jennifer Zuk, Jenya Iuzzini-Seigel, Kathryn Cabbage, Jordan R. Green & Tiffany P. Hogan
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 language impairment, speech delay, and typically developing peers.Method: Speech perception was measured by discrimination of synthesized speech syllable continua that varied in frequency (/dɑ/–/ɡɑ/)....

Speech perception, acoustics, and children (Iglehart, 2019)

Frank Iglehart
Purpose: The classroom acoustic standard ANSI/ASA S12.60-2010/Part 1 requires a reverberation time (RT) for children with hearing impairment of 0.3 s, shorter than its requirement of 0.6 s for children with typical hearing. While preliminary data from conference proceedings support this new RT requirement of 0.3 s, peer-reviewed data that support 0.3-s RT are not available on those wearing hearing aids. To help address this, this article compares speech perception performance by children with hearing...
