Three kinds of knowledge that effective teachers should master have been proposed: content knowledge (CK), pedagogical knowledge (PK), and pedagogical content knowledge (PCK). Most PCK studies have been conducted in the mathematics or science domain. In recent years, a growing number of studies related to foreign language teachers' PCK have…

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…

Children are adept at learning their language's speech-sound categories, but just how these categories function in their developing lexicon has not been mapped out in detail. Here, we addressed whether, in a language-guided looking procedure, 2-year-olds would respond to a mispronunciation of the voicing of the initial consonant of a newly learned…

Background: Stress production is important for effective communication, but this skill is frequently impaired in people with motor speech disorders. The literature reports successful treatment of these deficits in this population, thus highlighting the therapeutic potential of this area. However, no specific guidance is currently available to…

The Sylheti Bangla, a variety of Bangla language is primarily spoken in the Sylhet District of Bangladesh, Barak Valley of Assam, Tripura, especially in North Tripura. The systematic perusal on English spoken by Sylheti Bangla speakers demonstrates that it carries a huge difference with English (RP) specially in respect to pronunciation, syllable…

Purpose: Individuals with primary progressive apraxia of speech (PPAOS) have apraxia of speech (AOS) in which disruptions in articulation or prosody predominate the speech pattern, referred to, respectively, as phonetic or prosodic subtypes. Many develop aphasia and/or dysarthria. Past research has demonstrated that simple temporal acoustic…

Previous event-related potentials (ERP) research has investigated how foreign accent modulates listeners' neural responses to lexical-semantic and morphosyntactic errors. We extended this line of research to consider whether pronunciation errors in Mandarin Chinese are processed differently when a foreign-accented speaker makes them relative to…

Three categories of audio recordings, a web service platform, and commercial software were involved in this analysis process. The three categories of audio recordings included eight filtered student recordings, an audio recording provided by a Mandarin instructor from University Malaysia Sabah, and an audio recording generated by Text-to-Speech…

In this secondary analysis study, the authors explored the relations between reading comprehension and oral reading performance in fourth-grade students, using a data set from the U.S. National Assessment of Educational Progress (NAEP) special study of oral reading. The data set consisted of 1,713 students randomly selected from the 140,000 fourth…

Contrastive focus, conveyed by prosodic cues, marks important information. Studies have shown that 6-year-olds learning English and Japanese can use contrastive focus during online sentence comprehension: focus used in a "contrastive context" facilitates the identification of a target referent (speeding up processing), whereas focus used…

This study investigated how adult second language (L2) learners of Mandarin Chinese use knowledge of phonological and lexical statistical regularities when acoustic information is insufficient for word recognition. A gating task was used to test intermediate L2 learners at two time points across a semester of classroom learning. Native Mandarin…

Purpose: The function of child-directed speech has been debated for decades. This study examined the perceptual and acoustic characteristics of child- and adult-directed Cantonese tones to test the hyperarticulation and prosodic hypotheses that have been proposed to account for the acoustic modifications in child-directed speech. Method: Sixty-two…

This article extends Optimality Theoretic studies to the research on second language tone phonology. Specifically, this work analyses the acquisition of identical tone sequences in Mandarin Chinese by adult speakers of three non-tonal languages: English, Japanese and Korean. This study finds that the learners prefer not to use identical lexical…

This study explored the feasibility of training school teaching assistants to provide the treatment, Dynamic Temporal and Tactile Cueing to treat childhood apraxia of speech (CAS, also known as developmental verbal dyspraxia). The study used a single case experimental design across behaviours and a qualitative evaluation of teaching assistant…

This article reports on teachers' knowledge and perceptions and the issues they are concerned about in relation to pronunciation teaching. Understanding teacher cognition helps to ensure research and pedagogical advice are appropriately directed. However, there has been only a limited amount of research in this area. The researcher collected data…
