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…

Purpose: Apraxia of speech (AOS) is a motor speech disorder affecting articulatory planning and speech programming. When AOS is the sole manifestation of neurodegeneration, it is termed primary progressive apraxia of speech (PPAOS). Recent work has shown that there are distinct PPAOS subtypes: phonetic, prosodic, and those that do not clearly…

Justin Edward Bland – ProQuest LLC, 2023
The purpose of this dissertation is to examine the perception of unstressed vowel reduction (UVR)--also known as vowel devoicing--in Central Mexican Spanish. UVR is a variable, gradient process in which vowels undergo a constellation of phonetic weakening processes including shortening, devoicing, and apparent deletion (Gordon 1998). While it is…

Irena Lovcevic; Denis Burnham; Marina Kalashnikova – Language Learning and Development, 2024
There is a long-standing debate in the literature about the benefits that acoustic components of Infant Directed Speech (IDS) might have for infants' language acquisition. One of the highly contested features is vowel space expansion, which refers to the enlargement of the acoustic space between the corner vowels /i, u, a/ in IDS compared to Adult…

Osnat Segal; Dana Moyal – Journal of Speech, Language, and Hearing Research, 2024
Purpose: The purpose of the present study was to examine whether there is a listening preference for child-directed speech (CDS) over backward speech in moderate-preterm infants (MPIs). Method: Eighteen MPIs of gestational age of 32.0 weeks (range: 32-34.06 weeks), chronological age of 8.09 months, and maturation age of 6.48 months served as the…

McClay, Elise K.; Cebioglu, Senay; Broesch, Tanya; Yeung, H. Henny – Developmental Science, 2022
Infant-directed speech (IDS) is phonetically distinct from adult-directed speech (ADS): It is typically considered to have special prosody--like higher pitch and slower speaking rates--as well as unique speech sound properties, for example, more breathy, hyperarticulated, and/or variable consonant and vowel articulation. These phonetic features…

Kopecková, Romana; Wrembel, Magdalena; Gut, Ulrike; Balas, Anna – International Journal of Multilingualism, 2023
This study aims to investigate the nature of phonological awareness in young L3 learners, and the extent to which it changes over time as L2 and L3 learning progresses. Two groups of 12 closely matched multilinguals (total= 24, aged 12-13), who shared their L2 (English) but their L1/L3 (German/Polish) were mirrored, mimicked L2 and L3 accents in…

Steen, Vilde Buhaug; Englund, Nunne – Scandinavian Journal of Educational Research, 2022
This paper presents a natural experiment using a play situation with specific toys to examine and compare the characteristics of 33 Norwegian-speaking female pedagogical employees' child-directed speech (CDS) and adult-directed speech (ADS). Vowel pitch, duration, format frequency, and vowel space area of the vowels /a:/, /i:/, and /u:/ as well as…

Schwartz, Geoffrey – Second Language Research, 2020
This article discusses the implications of phonological representation for the study of L2 speech acquisition. It is argued, on the basis of empirical findings from diverse phenomena in L2 phonology, that refined representations in which 'segments' have internal prosodic structure offer a more insightful view of cross-linguistic phonetic…

Wang, Luchang; Kalashnikova, Marina; Kager, René; Lai, Regine; Wong, Patrick C. M. – Journal of Child Language, 2021
The functions of acoustic-phonetic modifications in infant-directed speech (IDS) remain a question: do they specifically serve to facilitate language learning via enhanced phonemic contrasts (the hyperarticulation hypothesis) or primarily to improve communication via prosodic exaggeration (the prosodic hypothesis)? The study of lexical tones…

Bazarbayeva, Z. M.; Amanbayeva, A. Zh.; Zhumabayeva, Zh. T.; Zhalalova, A. M. – Journal of Language and Linguistic Studies, 2021
Speech discourse is the communication between people, that is, the speaker seeks to influence the recipient in a conversation, using deep thoughts and meaningful words, expecting to receive a response from the addressee. In modern Kazakh linguistics, speech discourse is being explored in various ways as a reflection of people's relationships and…

Research on language learners' attention suggests that manipulating attention is beneficial in the language learning process as it facilitates the "noticing" of specific linguistic aspects. The current study investigated the effects of directing learners' attention to segments and prosody in English phonetic training. Korean learners of…

Schwartz, Geoffrey – Second Language Research, 2023
Two acoustic studies of voice onset time (VOT) in sibilant-stop (ST) consonant clusters, produced by first language (L1) speakers of Polish, are presented. In the first, a baseline study of L1 Polish comparing ST clusters with initial singleton stops, a small degree of VOT shortening after /s/ was found for /p/, but not /t/. The second study…

Marchenko, Valentyna – Journal of Language and Linguistic Studies, 2020
In the present research we look into the mechanisms which facilitate integrated functioning of speech and music components within a song. To understand the underlying mechanisms of such interaction we investigate poems set to music, analyzing the components of both speech and music intonation. The study is performed within the scope of Speech…

Gonzalez-Gomez, Nayeli; O'Brien, Frances; Harris, Margaret – Developmental Science, 2021
There is evidence showing that both maturational and environmental factors can impact on later language development. On the one hand, preterm birth has been found to increase the risk of deficits in the preschool and school years. Preterm children show poorer auditory discrimination, reading difficulties, poor vocabulary, less complex expressive…
