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…

Glotfelty, Annette; Katz, William F. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: To better understand the role of tongue visibility in speech, this study compared the spatiotemporal patterns of silent versus audible speech for lingual consonants of American English. Kinematic data were obtained for articulatory features assumed to be visually salient, including tongue movement (anterior displacement and midsagittal…

Vlahou, Eleni; Ueno, Kanako; Shinn-Cunningham, Barbara G.; Kopco, Norbert – Journal of Speech, Language, and Hearing Research, 2021
Purpose: We examined how consonant perception is affected by a preceding speech carrier simulated in the same or a different room, for different classes of consonants. Carrier room, carrier length, and carrier length/target room uncertainty were manipulated. A phonetic feature analysis tested which phonetic categories are influenced by the…

Overby, Megan S.; Caspari, Susan S.; Schreiber, James – Journal of Speech, Language, and Hearing Research, 2019
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…

Rebei, Adnan; Anderson, Nathaniel D.; Dell, Gary S. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2019
Every language has unique phonotactics, general rules about how phonemes combine to make syllables. We know that people can implicitly learn new phonotactic rules in the laboratory, and these rules then affect their speech errors. Some types of rules, however, require a consolidation period before they influence speech errors. Two experiments are…

Trecca, Fabio; McCauley, Stewart M.; Andersen, Sofie Riis; Bleses, Dorthe; Basbøll, Hans; Højen, Anders; Madsen, Thomas O.; Ribu, Ingeborg Sophie Bjønness; Christiansen, Morten H. – Language Learning, 2019
Research has shown that contoids (phonetically defined consonants) may provide more robust and reliable cues to syllable and word boundaries than vocoids (phonetically defined vowels). Recent studies of Danish, a language characterized by frequent long sequences of vocoids in speech, have suggested that the reduced occurrence of contoids may make…

Macrae, Toby – Language, Speech, and Hearing Services in Schools, 2017
Purpose: This clinical focus article provides readers with a description of the stimulus characteristics of 12 popular tests of speech sound production. Method: Using significance testing and descriptive analyses, stimulus items were compared in terms of the number of opportunities for production of all consonant singletons, clusters, and rhotic…

Sturm, Jessica L. – Foreign Language Annals, 2019
A body of previous work in second- and foreign language pronunciation instruction (e.g., Lord, 2005; Miller, 2012) has shown that explicit phonetic and pronunciation instruction is beneficial. However, Olson (2014) noted that just a few minutes per week of instruction are devoted to pronunciation in most classrooms. What is the effect of such…

Mersad, Karima; Dehaene-Lambertz, Ghislaine – Developmental Science, 2016
The auditory neural representations of infants can easily be studied with electroencephalography using mismatch experimental designs. We recorded high-density event-related potentials while 3-month-old infants were listening to trials consisting of CV syllables produced with different vowels (/bX/ or /gX/). The consonant remained the same for the…

Scott, John Hamilton Gordon – ProQuest LLC, 2019
Second language (L2) phonological acquisition involves learning novel target-language sounds, variable forms of sounds that arise in different phonological contexts, and any phonotactic constraints that govern their appearance. Interlanguage (IL) grammars must adapt to represent sounds and constraints that are novel to the native language (L1)…

Tamási, Katalin; Berent, Iris – Journal of Psycholinguistic Research, 2015
Linguistic evidence suggests that syllables like "bdam" (with stop-stop clusters) are less preferred than "bzam" (with stop-fricative combinations). Here, we demonstrate that English speakers manifest similar preferences despite no direct experience with either structure. Experiment 1 elicited syllable count for auditory…

Haley, Katarina L.; Jacks, Adam; Jarrett, Jordan; Ray, Taylor; Cunningham, Kevin T.; Gorno-Tempini, Maria Luisa; Henry, Maya L. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Of the three currently recognized variants of primary progressive aphasia, behavioral differentiation between the nonfluent/agrammatic (nfvPPA) and logopenic (lvPPA) variants is particularly difficult. The challenge includes uncertainty regarding diagnosis of apraxia of speech, which is subsumed within criteria for variant classification.…

Yurtbasi, Metin – International Online Journal of Primary Education, 2017
The three types of stresses namely "word stress," "compound stress" and "phrasal stress" are the key elements to determine the exact means of conveying a specific intent in an utterance. Therefore during perception and production of such meaning carrying codes, being able to use the right stress pattern is vitally…

Maionchi-Pino, Norbert; Taki, Yasuyuki; Yokoyama, Satoru; Magnan, Annie; Takahashi, Kei; Hashizume, Hiroshi; Ecalle, Jean; Kawashima, Ryuta – Journal of Experimental Child Psychology, 2013
To date, the nature of the phonological deficit in developmental dyslexia is still debated. We concur with possible impairments in the representations of the universal phonological constraints that universally govern how phonemes co-occur as a source of this deficit. We were interested in whether-and how-dyslexic children have sensitivity to…

Gangji, Nazneen; Pascoe, Michelle; Smouse, Mantoa – International Journal of Language & Communication Disorders, 2015
Background: Swahili is widely spoken in East Africa, but to date there are no culturally and linguistically appropriate materials available for speech-language therapists working in the region. The challenges are further exacerbated by the limited research available on the typical acquisition of Swahili phonology. Aim: To describe the speech…
