Purpose: This study examined how speakers adapt to fundamental frequency (f[subscript o]) errors that affect the use of prosody to convey linguistic meaning, whether f[subscript o] adaptation in that context relates to adaptation in linguistically neutral sustained vowels, and whether cue trading is reflected in responses in the prosodic cues of…

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…

This paper explored and analyzed features of English pronunciation that could cause intelligibility problems for Nepali English learners (ELs), who use English as a foreign language (EFL) or English as a second language (ESL). We examined the Nepali ELs' pronunciation issues by juxtaposing them with comparable segmental and suprasegmental features…

Previous research on infant-directed speech (IDS) and its role in infants' language development has largely focused on mothers, with fathers being investigated scarcely. Here we examine the acoustics of IDS as compared to adult-directed speech (ADS) in Norwegian mothers and fathers to 8-month-old infants, and whether these relate to direct…

The Mayan language Mam uses complex predicates to express events. Complex predicates map multiple semantic elements onto a single word, and consequently have a blend of lexical and phrasal features. The chameleon-like nature of complex predicates provides a window on children's ability to express phrasal combinations at the one-word stage of…

This study tested the effects of hand-clapping to the rhythm of newly learned French words on the pronunciation of these words by 7- to 8-year-old Catalan children. In a short training experiment with a pre- and posttest design, 28 children either repeated cognate words in French (e.g. French "aspirateur," Catalan "aspirador"…

In a language, certain phenomena are sensitive to specific prosodic domains. In a model of morphology-syntax-phonology interaction in which morphological and syntactic structure projects phonological domains belonging to a set hierarchy, each phonological process refers to a specific level of that hierarchy. Therefore, describing a phonological…

Computational models of child language development can help us understand the cognitive underpinnings of the language learning process, which occurs along several linguistic levels at once (e.g., prosodic and phonological). However, in light of the replication crisis, modelers face the challenge of selecting representative and consolidated infant…

Purpose: This scoping review considers the acoustic features of a clear speech register directed to nonnative listeners known as foreigner-directed speech (FDS). We identify vowel hyperarticulation and low speech rate as the most representative acoustic features of FDS; other features, including wide pitch range and high intensity, are still under…

Classic typologies within prosody tend to treat 'tone' languages as being diametrically opposed to 'stress' languages. However, Hyman (2006) highlights several languages that can have both, including Seneca, Fasu, and Copala Trique. As language documentation advances and our acoustic methodologies in the field are further refined, we have seen…

This study explores the effects of embodied prosodic training on the production of non-native French front rounded vowels (i.e. /y, ø, oe/) and the overall pronunciation proficiency. Fifty-seven Catalan learners of French practiced pronunciation in one of two conditions: one group observed hand gestures embodying prosodic features of the sentences…

Objective: We aimed to investigate the production of contrastive emphasis in French-speaking 4-year-olds and adults. Based on previous work, we predicted that, due to their immature motor control abilities, preschool-aged children would produce smaller articulatory differences between emphasized and neutral syllables than adults. Method: Ten…

Purpose: Phonetic variation due to domain initial strengthening was investigated with respect to the acoustic and articulatory distinctiveness of vowels within a subset of the French oral vowel system /i, e, ?, a, o, u/, organized along 4 degrees of height for the front vowels and 2 degrees of backness at the close and midclose height levels.…

Accurate and clear pronunciation is one of the most desirable features to achieve a successful communication. However, in Thailand, the pronunciation seems to be neglected in most skills. Mostly, students were forced to learn grammar and structure only. Consequently, Thai students, especially in a remote area where English native speakers were…

Millions engage in learning a Second Language (L2) using their mobile devices with a wide range of success. Concomitantly, there exists a growing interest in research on the effects of mobile-assisted language learning and predictors of learner outcomes (e.g., Loewen et al., 2020; Sudina & Plonsky, 2023). However, few of these apps and studies…
