In addition, measures associated with each memory stage were collected: Rapid digit naming provided an estimate...

Essential statistical concepts (Oleson et al., 2019)

Jacob J. Oleson, Grant D. Brown & Ryan McCreery
Purpose: Clinicians depend on the accuracy of research in the speech, language, and hearing sciences to improve assessment and treatment of patients with communication disorders. Although this work has contributed to great advances in clinical care, common statistical misconceptions remain, which deserve closer inspection in the field. Challenges in applying and interpreting traditional statistical methods with behavioral data from humans have led to difficulties with replication and reproducibility in other allied scientific fields, including psychology...

Retrieval-based word learning I (Leonard et al., 2019)

Laurence B. Leonard, Jeffrey Karpicke, Patricia Deevy, Christine Weber, Sharon Christ, Eileen Haebig, Sofía Souto, Justin B. Kueser &
Purpose: Scholars have long noted that retention improves significantly when learners frequently test themselves on the new material rather than engage in continuous study with no intermittent testing. In this study, we apply the notion of repeated testing or retrieval to the process of word learning in preschool-age children with and without developmental language disorder (DLD).Method: Novel words and their meanings were taught to 10 children with DLD and 10 typically developing (TD) children matched...

Progression of aphasia severity (Johnson et al., 2019)

Lisa Johnson, Alexandra Basilakos, Grigori Yourganov, Bo Cai, Leonardo Bonilha, Chris Rorden & Julius Fridriksson
Background and Purpose: The severity of aphasic impairment in chronic stroke survivors is typically thought to be stable by 6 months postonset. However, a recent study showed that stroke survivors with aphasia experience language improvement or decline in the chronic phase, years beyond onset. Little is known about why some individuals improve whereas others remain stable or decline. Additionally, no study has tracked changes in aphasia from assessments completed at multiple time points across many...

SRTn and brain volume (Rudner et al., 2019)

Mary Rudner, Mark Seeto, Gitte Keidser, Blake Johnson & Jerker Rönnberg
Purpose: Hearing loss is associated with changes in brain volume in regions supporting auditory and cognitive processing. The purpose of this study was to determine whether there is a systematic association between hearing ability and brain volume in cross-sectional data from a large nonclinical cohort of middle-aged adults available from the UK Biobank Resource (http://www.ukbiobank.ac.uk).Method: We performed a set of regression analyses to determine the association between speech reception threshold in noise (SRTn) and global...

Latent trait-naming ability estimates for the 2 PNT versions were analyzed in a...

Mandarin EL SR based on WaveNet-CTC (Qian et al., 2019)

, Li Wang, , Chan Liu &
Purpose: The application of Chinese Mandarin electrolaryngeal (EL) speech for laryngectomees has been limited by its drawbacks such as single fundamental frequency, mechanical sound, and large radiation noise. To improve the intelligibility of Chinese Mandarin EL speech, a new perspective using the automatic speech recognition (ASR) system was proposed, which can convert EL speech into healthy speech, if combined with text-to-speech.Method: An ASR system was designed to recognize EL speech based on a deep learning...

Retrospective study of early characteristics (Overby et al., 2019)

Megan S. Overby, Susan S. Caspari & James Schreiber
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 and toddlers as LCAS. Extant studies also often lack a comparison group of infants and toddlers who were later diagnosed, as older children, with a speech sound...

Purpose: The ability of 5- and 6-year-old male children (23 participants) between the chronological ages of 5;0 and 6;11(years;months) with childhood apraxia of speech (CAS; n = 9) and with typical development (TD; n = 14) to detect differences in vowel duration of syllable pairs is explored. We asked whether the children with CAS show different patterns of performance on the vowel duration difference experimental task than those of their similarly aged peers with TD.Method:...

Vocal Development Landmarks Interview (Moeller et al., 2019)

Mary Pat Moeller, Anne E. Thomas, Jacob Oleson & Sophie E. Ambrose
Purpose: Tracking of infants’ progression through early vocal stages supports the identification of children at risk for language delays and guides early intervention for children with disabilities. However, few clinical tools are available to support systematic assessment of infants’ early vocal development. This study sought to develop and conduct a preliminary evaluation of the validity of a parent report tool designed for this purpose, the Vocal Development Landmarks Interview (VDLI).Method: The participants were caregivers of...

Dual-task performance in Parkinson disease (Whitfield et al., 2019)

Jason A. Whitfield, Zoe Kriegel, Adam M. Fullenkamp &
Purpose: Prior investigations suggest that simultaneous performance of more than 1 motor-oriented task may exacerbate speech motor deficits in individuals with Parkinson disease (PD). The purpose of the current investigation was to examine the extent to which performing a low-demand manual task affected the connected speech in individuals with and without PD.Method: Individuals with PD and neurologically healthy controls performed speech tasks (reading and extemporaneous speech tasks) and an oscillatory manual task (a counterclockwise circle-drawing...

Optimized and predictive phonemic interfaces (Cler et al., 2019)

Gabriel J. Cler, Katharine R. Kolin, Jacob P. Noordzij, Jennifer M. Vojtech, Susan K. Fager & Cara E. Stepp
Purpose: We empirically assessed the results of computational optimization and prediction in communication interfaces that were designed to allow individuals with severe motor speech disorders to select phonemes and generate speech output.Method: Interface layouts were either random or optimized, in which phoneme targets that were likely to be selected together were located in proximity. Target sizes were either static or predictive, such that likely targets were dynamically enlarged following each selection. Communication interfaces were evaluated...

Fundamental frequency and rate on synthetic speech (Vojtech et al., 2019)

Jennifer M. Vojtech, Jacob P. Noordzij, Gabriel J. Cler & Cara E. Stepp
Purpose: This study investigated how modulating fundamental frequency (f0) and speech rate differentially impact the naturalness, intelligibility, and communication efficiency of synthetic speech.Method: Sixteen sentences of varying prosodic content were developed via a speech synthesizer. The f0 contour and speech rate of these sentences were altered to produce 4 stimulus sets: (a) normal rate with a fixed f0 level, (b) slow rate with a fixed f0 level, (c) normal rate with prosodically natural f0 variation,...

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...

Multilingual DHH SR (Crowe & Guiberson, 2019)

Kathryn Crowe & Mark Guiberson
Purpose: Many educators and speech-language pathologists have difficulty providing effective interventions to the growing population of d/Deaf and hard-of-hearing (DHH) learners who use more than 1 language. The purpose of this review article was to identify evidence-based interventions for speech, language, and literacy used with DHH multilingual learners (DMLs), monolingual DHH learners, and hearing bilingual learners without hearing loss. Interventions used with these groups can inform the practice of professionals providing services to DMLs.Method: This...
