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…

Due to the difficulties of speech signal processing, there is still a considerable gap between the ability of machines to correctly process and that of human beings. In order to overcome the defects of isolated learning and noise sensitivity of SOM, this paper proposes a new time self-organization model (TSOM) from the perspective of deep…

Psycholinguistic research on children's early language environments has revealed many potential challenges for language acquisition. One is that in many cases, referents of linguistic expressions are hard to identify without prior knowledge of the language. Likewise, the speech signal itself varies substantially in clarity, with some productions…

Infants' preference for vowelharmony (VH, a phonotactic constraint that requires vowels in a word to be featurally similar) is thought to be language-specific: Monolingual infants learning VH languages show a listening preference for VH patterns by 6 months of age, while those learning non-VH languages do not (Gonzalez-Gomez et al., 2019; Van…

Purpose: We evaluated whether children whose inaccurate /[voiced alveolar approximant]/ productions showed evidence phonetic differentiation with /w/ at 3.5-4.5 years of age improved in /[voiced alveolar approximant]/ production over the next year more than children whose inaccurate productions did not show evidence of such differentiation. We…

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…

In linguistics, onomastics is the science that studies the history and origin of toponyms, along with their structural aspects. This study aimed to determine the origin of toponyms by comparing their linguistic and ethnocultural, as well as mythical, information. A qualitative research design guided this study. A few toponyms were identified…

The role of phonological awareness and alphabet knowledge in learning to read is well established in mono-lingual English speakers. However, it is under explored in the context of English Language Learners (ELL), especially in regions like India where the native language differs phonologically and orthographically from the target literate…

Dyslexia is a reading disability affecting a large number of people worldwide. People with dyslexia have at least normal levels of intelligence, yet they nevertheless have significant difficulties with reading. Dyslexia is known to have genetic causes; however, some researchers believe that there are also environmental factors at play.…

Purpose: This study builds upon an established effective training method to investigate the advantages of high variability phonetic identification training for enhancing lexical tone perception and production in Mandarin-speaking pediatric cochlear implant (CI) recipients, who typically face ongoing challenges in these areas. Method: Thirty-two…

This study explored the production of 11 English vowels by Acehnese Indonesian EFL students. Ten undergraduates (five males and five females) from the Pidie District, Aceh, participated, with Acehnese and Bahasa Indonesia as their first languages, and English learned formally at school since the 7th grade. Using PRAAT, recordings of vowel…

Although current approaches to second language (L2) pronunciation underscore that instruction should concentrate on pronunciation features that help learners be more intelligible (and not necessarily more native like), there is little empirical evidence as to what those features are, especially in languages other than English. To address this gap,…

This dissertation explores the relationship between quantitative phonetic measurements and listener identification of accents of English, focusing on phonetic distance and its perceptual correlates across various English accent varieties. The Levenshtein distance (LD) measure, which quantifies string similarity by calculating the minimum cost of…

This article follows Johnson and Liddell (2011a, 2011b, 2011c, 2012) and Liddell and Johnson (2019), which introduce the concepts of sequentiality and contrast, a segmental framework consisting of postures and trans-forms, and features describing the configuration of the fingers and of the thumb. This article further develops that theory of…

The use of phonetic symbols in language teaching classrooms, as a bottom-up approach to pronunciation instruction, has been debated. This study investigates the perspectives of Turkish instructors of English as a foreign language on their use of phonetic symbols for teaching pronunciation at tertiary-level institutions. To explore this issue,…
