Mastering the phonological aspects of a second language (L2) poses significant challenges for adult learners, often affecting their intelligibility in acquiring that language (Derwing, Munro, & Wiebe, 1998). McAllister (1997) has highlighted L2 learners' struggles in perceiving and producing novel segmental features, which is corroborated by…

The effects of international phonetic alphabet (IPA) instruction on English as a foreign language (EFL) adult learners' pronunciation have been well-recognized. However, not many studies on the topic were conducted in the Vietnamese context. Therefore, the current study aims to investigate (1) the impact of IPA learning on Vietnamese EFL adult…

This study explores ESL learners' perceptions of using high-variability phonetic training (HVPT) through YouGlish to improve pronunciation skills. Data were collected through an online questionnaire completed by 70 upper-intermediate level ESL learners and semistructured interviews with 20 learners. The collected data were analyzed statistically…

Although second language (L2) learners often have difficulty with learning the L2 pronunciation, the literature has reported a mix of more successful and less successful learners. Many factors could contribute to individual variation in L2 speech sound learning. This dissertation examines a few factors that are hypothesized to influence L2…

An extensive number of corrective feedback (CF) studies have examined learners' errors with grammar, vocabulary, pronunciation, and spelling (non-formulaic forms) and established an association between learners' uptake of CF and their second language development. However, learners' errors with formulaic sequences (FSs) comprising idioms,…

Instruction in second language (L2) English phoneme pronunciation almost invariably includes a focus on improving the learners' use of their articulatory organs to pronounce the relevant sounds. However, the pronunciation of many English sounds also relies on effort from the abdominal region, and under-utilization of this region can often…

In commercial materials for the teaching of second language (L2) pronunciation, common bottom-up approaches segment phonology into a series of discrete and decontextualized linguistic components with rules that students are encouraged to internalize. Such approaches seem out of step with recent second language acquisition (SLA) theory and research…

Adult second language (L2) learning often exhibits great variability in its rate and outcome. Although research shows that learning trajectories are partly shaped by social and contextual factors (e.g. Larson-Hall, 2008), certain learner factors play an important role in enhancing L2 pronunciation learning by helping L2 learners notice and process…

Adult Japanese speakers often experience difficulty learning English /r/-/l/. Previous research has reported the effectiveness of using perception-based high-variability identification training with natural speech stimuli on improving Japanese speakers' perception and production of /r/-/l/. Recent studies have also shown the effectiveness of using…

In today's interconnected world, increasing longevity has elevated the societal role of older adults, fostering their active participation. Education, particularly language learning supported by technology, empowers this demographic to thrive in a globalized society. Integrating Information and Communication Technologies (ICT) into language…

The aim of the study was to identify the factors that contribute to speaking anxiety in Thai adult EFL learners working in an online media company and enrolled in an English course provided by the company, as well as to discover the anxiety reduction techniques used by these learners. The results showed that significant contributors to speaking…

Like other performance-based subjects such as theater or music, pronunciation is heavily time-dependent because students need plentiful opportunities to receive input, practice skills, and get coaching and feedback from their teachers. When the Language Education and Partnerships Intensive English Program at Wright State University offered a…

Oral communication is one of the main reasons language learners attend language classes. As pronunciation is among the most significant aspects of oral communication, this study attempted to see how learning-oriented assessment (LOA) could affect pronunciation learning of Iranian EFL learners. To this end, 64 language learners in a private…

Twenty adult ESL students at a community college participated in a semester reading intervention. Participants received a modified extensive reading treatment, and some participants received an additional repeated reading direct instruction reading intervention. The author examined the impact of the reading interventions on ESL students' reading…

This paper sets out to peruse the role of various theories or more precisely, hypotheses invoked in second language acquisition (SLA) research by surveying three empirical studies pertaining to the critical period hypothesis in the SLA of phonetics and phonology. In particular, the three studies reviewed are titled in chronological order as (1)…
