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…

In the study of English in a bilingual environment, issues related to the need to develop students' phonetic and lexical competencies, which include communication, phonetic and auditory skills and lexical sufficiency, are of particular relevance. The motive of this study is the need to improve the methodology of teaching English in the context of…

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…

Background: Phonetic transcription of disordered speech samples is especially crucial for the assessment and treatment of functional or organic speech-sound disorders. Previous studies show that students who struggle with the identification and segmentation of speech sounds are more likely to encounter difficulties with clinical phonetic…

Background: Previous work suggests that children can teach themselves new written words via reading aloud texts independently (i.e., orthographic learning via self-teaching). In self-teaching in Chinese, regular phonetic radicals and transparent semantic radicals facilitate orthographic learning. The present study examined the roles of phonetic…

Increasing phonological awareness of children with special needs is of vital importance, as it helps them to face different problems they face. Therefore, this study assessed the efficacy of implementing an instructional program to raise phonological awareness in improving the phonetic sequential-memorisation ability of students with learning…

An introductory phonetics course provides foundational content for future clinical practice and may serve as a student's first experience within the field of Communication Sciences and Disorders. The Students as Partners framework (Cook-Sather et al., 2014) offers a model for valuing student assets and experiences in co-creating learning materials…

The extant studies addressing second language phonetic perception assume that second language phonemes are perceived to be similar to first language phonemes, and tend to be substituted by learners of English as a foreign language. This study aimed to assess the perceptual relationship between the phonemes of English and the sound units of Omani…

Purpose: Individuals vary in their ability to learn the sound categories of nonnative languages (nonnative phonetic learning) and to adapt to systematic differences, such as accent or talker differences, in the sounds of their native language (native phonetic learning). Difficulties with both native and nonnative learning are well attested in…

Background: Phonetic transcription is recognized in regulatory standards as an essential skill for Speech and Language Therapists (SLTs) in the assessment, diagnosis and management of clients with speech difficulties. Previous research has identified that approaches to phonetic transcription vary, and that SLTs often lack confidence in…

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…

This study aims to investigate the improvement of EFL students' English pronunciation skills by using English phonetic alphabet drills. The samples of this study were 35 first-year students of English for International Communication major, Faculty of Humanities and Social Sciences, Rajamangala University of Technology Tawan-ok. They all registered…

Spoken word recognition depends on variations in fine-grained phonetics as listeners decode speech. However, many models of second language (L2) speech perception focus on units such as isolated syllables, and not on words. In two eye-tracking experiments, we investigated how fine-grained phonetic details (i.e. duration of nasalization on…

In the first year of life, infants' speech perception becomes attuned to the sounds of their native language. This process of early phonetic learning has traditionally been framed as phonetic category acquisition. However, recent studies have hypothesized that the attunement may instead reflect a perceptual space learning process that does not…

Speakers vary in their pronunciations of the sounds in their native language. Listeners use lexical knowledge to adjust their phonetic categories to speakers' idiosyncratic pronunciations. Lexical information can, however, be inconclusive or become available too late to guide this phonetic retuning. Sentence context is known to affect lexical…
