Tristan J. Mahr; Paul J. Rathouz; Katherine C. Hustad – Journal of Speech, Language, and Hearing Research, 2025
Purpose: Earlier work has established developmental benchmarks for intelligibility and articulation rate, but the intersection of these two variables, especially within individual children, has received limited attention. This study examines the interaction between intelligibility and speaking rate in typically developing children between the ages…

Cassandra Alighieri; Andrew Hodges; Jolien Verbeke; Katrien Kestens; Kim Bettens; Rica Albite; Raphaelle May Tan; Kristiane Van Lierde – International Journal of Language & Communication Disorders, 2025
Background: Adults presenting with unrepaired cleft palate are not a rare occurrence in middle-income countries. However, many surgeons are hesitant to operate on these individuals because of the challenges in repairing the wide adult cleft palate, as well as concerns regarding any improvement in speech in older patients. Unfortunately, the…

Elizabeth Krajewski; Jimin Lee; Annie J. Olmstead; Zachary Simmons – Journal of Speech, Language, and Hearing Research, 2024
Purpose: In this study, we examined the utility of vowel intelligibility testing for assessing the impact of dysarthria on speech characteristics in people with amyotrophic lateral sclerosis (ALS). We tested the sensitivity and specificity of overall vowel identification, as well as that of vowel-specific identification, to dysarthria presence and…

Doyle, Philip C.; Baker, Adrienne M. H.; Evitts, Paul M. – International Journal of Language & Communication Disorders, 2023
Background: There is a large body of research showing the negative impact of a total laryngectomy on the resultant voice signal across multiple outcomes (e.g., speech intelligibility/acceptability, listener comprehension, voice quality). However, there is limited information on the effects of laryngectomy on broader communication acts,…

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…

Meisam K. Arjmandi; Jean Neils-Strunjas; Samaneh Nemati; Julius Fridriksson; Sarah Newman-Norlund; Roger Newman-Norlund; Leonardo Bonilha – Journal of Speech, Language, and Hearing Research, 2024
Purpose: Aging increases risk for hearing loss, cognitive decline, and social isolation; however, the nature of their interconnection remains unclear. This study examined the interplay between age-related hearing loss, cognitive decline, and social isolation in adults by testing the ability to understand speech in background noise, a challenge…

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…

Inceoglu, Solène; Chen, Wen-Hsin; Lim, Hyojung – ReCALL, 2023
An increasing number of studies are exploring the benefits of automatic speech recognition (ASR)-based dictation programs for second language (L2) pronunciation learning (e.g. Chen, Inceoglu & Lim, 2020; Liakin, Cardoso & Liakina, 2015; McCrocklin, 2019), but how ASR recognizes accented speech and the nature of the feedback it provides to…

Crowther, Dustin; Holden, Daniel; Urada, Kristen – Language Teaching, 2022
Published in "Language Learning" in 1995, Munro and Derwing's* investigation of foreign accent, comprehensibility, and intelligibility in second language (L2) speech instigated significant change in L2 pronunciation research (Levis, 2020). A key finding was that despite the presence of a foreign accent, listeners could indeed comprehend…

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…

Pommée, Timothy; Balaguer, Mathieu; Mauclair, Julie; Pinquier, Julien; Woisard, Virginie – International Journal of Language & Communication Disorders, 2022
Background: Intelligibility and comprehensibility in speech disorders can be assessed both perceptually and instrumentally, but a lack of consensus exists regarding the terminology and related speech measures in both the clinical and scientific fields. Aims: To draw up a more consensual definition of intelligibility and comprehensibility and to…

Nagle, Charles L.; Trofimovich, Pavel; O'Brien, Mary Grantham; Kennedy, Sara – Studies in Second Language Acquisition, 2022
Comprehensibility, or ease of understanding, has emerged as an important construct in second language (L2) speech research. Many studies have examined the linguistic features that underlie this construct, but there has been limited work on behavioral and affective predictors. The goal of this study was therefore to examine the extent to which…

Huensch, Amanda; Nagle, Charlie – Studies in Second Language Acquisition, 2022
This report examines the potential impacts of task and proficiency on listener judgments of intelligibility, comprehensibility, and accentedness in L2 Spanish. This study extends Huensch and Nagle ["Language Learning," 71, 626-668, (2021)], who explored the partial independence among the global speech dimensions for speech samples taken…
