Noiray, Aude; Wieling, Martijn; Abakarova, Dzhuma; Rubertus, Elina; Tiede, Mark – Journal of Speech, Language, and Hearing Research, 2019
Purpose: This study examines the temporal organization of vocalic anticipation in German children from 3 to 7 years of age and adults. The main objective was to test for nonlinear processes in vocalic anticipation, which may result from the interaction between lingual gestural goals for individual vowels and those for their neighbors over time.…

Max, Ludo; Dalin, Ayoub – Journal of Speech, Language, and Hearing Research, 2019
Purpose: We review and interpret our recent series of studies investigating motor-to-auditory influences during speech movement planning in fluent speakers and speakers who stutter. In those studies, we recorded auditory evoked potentials in response to probe tones presented immediately prior to speaking or at the equivalent time in no-speaking…

Rong, Panying; Green, Jordan R. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), have a devastating effect on speech muscle function that often results in severe communication deficits. Over the course of bulbar disease, tongue and jaw movements are modified, but their impact on speech is poorly understood. The aim of this study was to determine the…

Redford, Melissa A. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Current approaches to speech production aim to explain adult behavior and so make assumptions that, when taken to their logical conclusion, fail to adequately account for development. This failure is problematic if adult behavior can be understood to emerge from the developmental process. This problem motivates the proposal of a…

Terband, Hayo; Namasivayam, Aravind; Maas, Edwin; van Brenk, Frits; Mailend, Marja-Liisa; Diepeveen, Sanne; van Lieshout, Pascal; Maassen, Ben – Journal of Speech, Language, and Hearing Research, 2019
Background: With respect to the clinical criteria for diagnosing "childhood apraxia of speech" (commonly defined as a disorder of speech motor planning and/or programming), research has made important progress in recent years. Three segmental and suprasegmental speech characteristics--error inconsistency, lengthened and disrupted…

de Boer, Bart – Journal of Speech, Language, and Hearing Research, 2019
Purpose: This article critically reviews work on the evolution of speech in the context of motor control. It presents a brief introduction to the field of language evolution, of which the study of the evolution of speech is an integral component, and argues why taking the evolutionary perspective is useful. It then proceeds to review different…

Aichert, Ingrid; Lehner, Katharina; Falk, Simone; Späth, Mona; Ziegler, Wolfram – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Earlier investigations based on word and sentence repetition tasks had revealed that the most prevalent metrical pattern in German (the trochee)--unlike the iambic pattern--facilitates articulation in patients with apraxia of speech (AOS; e.g., Aichert, Späth, & Ziegler, 2016), confirming that segmental and prosodic aspects of speech…

Tourville, Jason A.; Nieto-Castañón, Alfonso; Heyne, Matthias; Guenther, Frank H. – Journal of Speech, Language, and Hearing Research, 2019
Neuroimaging has revealed a core network of cortical regions that contribute to speech production, but the functional organization of this network remains poorly understood. Purpose: We describe efforts to identify reliable boundaries around functionally homogenous regions within the cortical speech motor control network in order to improve the…

Parrell, Benjamin; Houde, John – Journal of Speech, Language, and Hearing Research, 2019
Purpose: While the speech motor system is sensitive to feedback perturbations, sensory feedback does not seem to be critical to speech motor production. How the speech motor system is able to be so flexible in its use of sensory feedback remains an open question. Method: We draw on evidence from a variety of disciplines to summarize current…

Garnett, Emily O.; Chow, Ho Ming; Chang, Soo-Eun – Journal of Speech, Language, and Hearing Research, 2019
Purpose: We review two recent neuroanatomical studies of children who stutter (CWS), one that examines white matter integrity and the other that focuses on cortical gray matter morphology. In both studies, we sought to examine differences between children whose stuttering persists ("persistent"), children who recovered from stuttering…

Brosseau-Lapré, Françoise; Roepke, Elizabeth – Journal of Speech, Language, and Hearing Research, 2019
Purpose: The aim of this study was to examine the relationship between types of speech errors produced by children with speech sound disorders (SSD) and children with typical speech and language development (TD) and phonological awareness (PA) skills. Method: Participants were 40 children, half with SSD and half with TD, ages 4 and 5 years. They…

Stone, Maureen; Gomez, Arnold D.; Zhuo, Jiachen; Tchouaga, Ange Lydie; Prince, Jerry L. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Anterior tongue shape during /s/ production is often described as "tip-up" or apical, versus "tipdown" or laminal. Typically, this is determined by observing the shape of the anterior midline tongue. The purpose of this study was to identify methods of curvature calculation that quantify the observed shape differences…

Vermeire, Katrien; Knoop, Allart; De Sloovere, Marleen; Bosch, Peggy; van den Noort, Maurits – Journal of Speech, Language, and Hearing Research, 2019
Purpose: The purpose of this study was to investigate the relationship between working memory (WM) capacity and speech recognition in noise in both a group of young adults and a group of older adults. Method: Thirty-three older adults with a mean age of 71.0 (range: 60.4-82.7) years and 27 young adults with a mean age of 21.7 (range: 19.1-25.0)…

Aithal, Sreedevi; Aithal, Venkatesh; Kei, Joseph; Manue, Alehandrea – Journal of Speech, Language, and Hearing Research, 2019
Objective: This study investigated pressurized transient evoked otoacoustic emission (TEOAE) responses and wideband absorbance (WBA) in healthy ears and ears with negative middle ear pressure (NMEP). Method: In this cross-sectional study, TEOAE amplitude, signal-to-noise ratio, and WBA were measured at ambient and tympanometric peak pressure (TPP)…

Davidson, Lisa S.; Geers, Ann E.; Uchanski, Rosalie M.; Firszt, Jill B. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: The overall goal of the current study was to identify an optimal level and duration of acoustic experience that facilitates language development for pediatric cochlear implant (CI) recipients--specifically, to determine whether there is an optimal duration of hearing aid (HA) use and unaided threshold levels that should be considered…
