This dissertation examines whether EFL and ESL Korean learners of English are able to produce and perceive two English phonological contrasts that depend on vowel duration differences, coda consonant voicing contrasts and the tense-lax distinction in vowels. For production, it examines differences in vowel duration and vowel quality associated…

Purpose: This study aims at investigating the phonological development of the six guttural consonants of Jordanian Arabic, /[chi]/, /[voiced uvular fricative]/, /[voiceless pharyngeal fricative]/, /[voiced pharyngeal fricative]/, /[glottal stop]/, and /h/. Method: An articulation test is designed to involve two tasks: picture naming and…

As children learn to read, they become sensitive to context-dependent vowel pronunciations in words, considered a form of statistical learning. The work of Treiman and colleagues demonstrated that readers' vowel pronunciations depend on the consonantal context in which the vowel occurs and reading experience. Using explanatory item-response models…

Purpose: This article reports on the effectiveness of a novel tablet-based approach to phonological intervention and compares it to a traditional tabletop approach, targeting children with phonologically based speech sound disorders (SSD). Method: Twenty-two Portuguese children with phonologically based SSD were randomly assigned to 1 of 2…

The Arabic writing system allows for two representations: vowelized or non-vowelized. The vowelized writing, which characterizes the writing in the Koran, classical literature and children's books, includes the long and short vowels and all the vowels, including the vowels that express syntax functions (the final vowels). In non-vowelized writing,…

An insufficient number of studies investigated the criteria for Arabic letter teaching in schools. Teachers play an integral role in understanding Arabic letters among young children, as it is essential for acquiring reading in the Arabic language early in life. The criteria for teaching letters in a current study include ease of pronunciation,…

Dyslexia is a neuro-sensory issue that makes reading challenging. However, Dyslexic Phonemic R[subscript 3] is a novel approach that improved the phonological development and resolved the reading challenges of dyslexia. The primary goal of the study was (1) to evaluate the current state of the phonemic and auditory symptoms of children with…

Purpose: Children with hearing loss (HL), including those with hearing aids (HAs) and cochlear implants (CIs), often have difficulties contrasting words like "beach" versus "peach" and "dog" versus "dock" due to challenges producing systematic voicing contrasts. Even when acoustic contrasts are present,…

The extent of quantitative and qualitative differences in phonological development between bilingual children and their monolingual counterparts remains unresolved, especially with regard to typologically-related languages. The current study used a comparative research design to examine the phonological skills of preschool children speaking Polish…

Purpose: The aim of this study was to investigate children's acquisition of Vietnamese speech sounds. Method: Participants were 195 children aged 2;2-5;11 (years;months) living in Northern Viet Nam who spoke Vietnamese as their 1st language. Single-word samples were collected using the Vietnamese Speech Assessment (Ph?m, Le, & McLeod, 2016) to…

Purpose: This study investigated Icelandic-speaking children's acquisition of singleton consonants and consonant clusters. Method: Participants were 437 typically developing children aged 2;6-7;11 (years;months) acquiring Icelandic as their first language. Single-word speech samples of the 47 single consonants and 45 consonant clusters were…

Three novel experiments investigated the effectiveness of color-coded word-families flashcards for facilitating kindergarteners' word recognition skills. Flashcards were constructed with the rime of the word family (vowel and remaining consonant sounds) printed in black ink, indicating that words with this spelling pattern sound the same, and the…

The study assessed the clinical utility of an invented spelling tool and determined whether invented spelling with linguistic manipulation at segmental and supra-segmental levels can be used to better identify reading difficulties. We conducted linguistic manipulation by using real and nonreal words, incorporating word stress, alternating the…

Recent efforts to motivate parents' involvement in their child's literacy development involve informing parents about how to incorporate literacy development into daily routines. Teacher leadership and communication are critical--the more teachers encourage and assist parents and caregivers in supporting their child's literacy development, the…

Purpose: It is generally accepted that adults use visual cues to improve speech intelligibility in noisy environments, but findings regarding visual speech benefit in children are mixed. We explored factors that contribute to audiovisual (AV) gain in young children's speech understanding. We examined whether there is an AV benefit to…
