Keiko Ishikawa; Hannah Li; Elisabeth Coster – Journal of Speech, Language, and Hearing Research, 2023
Background/Objectives: The objectives of this study were to explore (a) the influence of different types of background noise and their informational content on the ability of speakers to initiate and maintain clear speech (CS), a widely utilized technique for enhancing speech intelligibility, and (b) the impact of background noise and CS usage on…

Nicholas A. Smith; Christine A. Hammans; Timothy J. Vallier; Bob McMurray – Journal of Speech, Language, and Hearing Research, 2024
Purpose: Talkers adapt their speech according to the demands of their listeners and the communicative context, enhancing the properties of the signal (pitch, intensity) and/or properties of the code (enhancement of phonemic contrasts). This study asked how mothers adapt their child-directed speech (CDS) in ways that might serve the immediate goals…

Is L2 Pronunciation Affected by Increased Task Complexity in Pronunciation-Unfocused Speaking Tasks?
Ingrid Mora-Plaza; Joan C. Mora; Mireia Ortega; Cristina Aliaga-Garcia – Studies in Second Language Acquisition, 2024
This study examines the effects of task complexity on second language (L2) pronunciation accuracy and global pronunciation measures in pronunciation-unfocused tasks and assesses the relationship between acoustic and listener-based pronunciation measures. Eighty-two Catalan/Spanish learners of English performed simple and complex versions of a…

Kim, Yoonji; Sidtis, Diana; Sidtis, John J. – Journal of Speech, Language, and Hearing Research, 2023
Purpose: This study examined spontaneous, spoken-to-a-model, and two sung modes in speakers with Parkinson's disease (PD), speakers with cerebellar disease (CD), and healthy controls. Vocal performance was measured by intelligibility scores and listeners' perceptual ratings. Method: Participants included speakers with hypokinetic dysarthria…

Sarah E. Yoho; Tyson S. Barrett; Stephanie A. Borrie – Journal of Speech, Language, and Hearing Research, 2023
Purpose: The ability to understand speech under adverse listening conditions is highly variable across listeners. Despite this, studies have found that listeners with normal hearing display consistency in their ability to perceive speech across different types of degraded speech, suggesting that, for at least these listeners, global skills may be…

Cuartero, Marie-Charlotte; Bertrand, Roxane; Rauzy, Stéphane; Véron-Delor, Lauriane; Atkinson-Clement, Cyril; Grabli, David; Vidailhet, Marie; Pinto, Serge – International Journal of Language & Communication Disorders, 2021
Background: Hyperkinetic dysarthria is often present in isolated dystonia (ID) and is still understudied. Four main clusters of deviant speech dimensions in dystonia hyperkinetic dysarthria were initially provided: articulatory inaccuracy, phonatory stenosis, prosodic excess and prosodic insufficiency. Aim: The aim of our exploratory study was to…

Lauren Petley; Chelsea Blankenship; Lisa L. Hunter; Hannah J. Stewart; Li Lin; David R. Moore – Journal of Speech, Language, and Hearing Research, 2024
Purpose: Amplitude modulations (AMs) are important for speech intelligibility, and deficits in speech intelligibility are a leading source of impairment in childhood listening difficulties (LiD). The present study aimed to explore the relationships between AM perception and speech-in-noise (SiN) comprehension in children and to determine whether…

Hoyoung Yi; Moumita Choudhury; Candace Hicks – Journal of Speech, Language, and Hearing Research, 2023
Purpose: The purpose of the study is to investigate the impacts of a surgical mask and a transparent mask on audio-only and audiovisual speech intelligibility in noise (i.e., 0 dB signal-to-noise ratio) in individuals with mild-to-profound hearing loss. The study also examined if individuals with hearing loss can benefit from using a transparent…

Nguyen, Duy Duong; Chacon, Antonia; Payten, Christopher; Black, Rebecca; Sheth, Meet; McCabe, Patricia; Novakovic, Daniel; Madill, Catherine – International Journal of Language & Communication Disorders, 2022
Background: Previous research has found that high-frequency energy of speech signals decreased while wearing face masks. However, no study has examined the specific spectral characteristics of fricative consonants and vowels and the perception of clarity of speech in mask wearing. Aims: To investigate acoustic-phonetic characteristics of fricative…

Gianakas, Steven P.; Fitzgerald, Matthew B.; Winn, Matthew B. – Journal of Speech, Language, and Hearing Research, 2022
Purpose: An extra moment after a sentence is spoken may be important for listeners with hearing loss to mentally repair misperceptions during listening. The current audiologic test battery cannot distinguish between a listener who repaired a misperception versus a listener who heard the speech accurately with no need for repair. This study aims to…

Thomas, Anusha; Teplansky, Kristin J.; Wisler, Alan; Heitzman, Daragh; Austin, Sara; Wang, Jun – Journal of Speech, Language, and Hearing Research, 2022
Purpose: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects bulbar functions including speech and voice. Voice onset time (VOT) was examined in speakers with ALS in early and late stages to explore the coordination of the articulatory and phonatory systems during speech production. Method: VOT was measured in nonword…

Mark A. Eckert; Lois J. Matthews; Kenneth I. Vaden Jr.; Judy R. Dubno – Journal of Speech, Language, and Hearing Research, 2024
Purpose: Speech recognition in noise is challenging for listeners and appears to require support from executive functions to focus attention on rapidly unfolding target speech, track misunderstanding, and sustain attention. The current study was designed to test the hypothesis that lower executive function abilities explain poorer speech…

Stephanie A. Borrie; Taylor J. Hepworth; Camille J. Wynn; Katherine C. Hustad; Tyson S. Barrett; Kaitlin L. Lansford – Journal of Speech, Language, and Hearing Research, 2023
Purpose: As evidenced by perceptual learning studies involving adult listeners and speakers with dysarthria, adaptation to dysarthric speech is driven by signal predictability (speaker property) and a flexible speech perception system (listener property). Here, we extend adaptation investigations to adolescent populations and examine whether adult…

Murgia, Silvia; Webster, JosseMia; Cutiva, Lady Catherine Cantor; Bottalico, Pasquale – Language, Speech, and Hearing Services in Schools, 2023
Purpose: Good verbal signals and low background noise are key factors for all children to maximize understanding of what is being taught. Classroom shape, surroundings, and even furnishings change how the environment "sounds" and how speech is "heard" in the classroom. Classroom acoustics is perhaps one of the most important,…

Guerra, Giada; Tijms, Jurgen; Vaessen, Anniek; Tierney, Adam; Dick, Frederic; Bonte, Milene – Mind, Brain, and Education, 2021
Reading skills are usually assessed in silent conditions, but children often experience noisy educational settings. Effects of auditory distraction on children's reading skills remain relatively unexplored. The present study investigates the influence of two features of background speech--intelligibility and loudness--on children's reading speed…
