An important shift in language learning research is the understanding that pronunciation instruction is necessary to ensure learners' balanced development in pronunciation and second language (L2) speech. Research focusing on understanding what types of pronunciation instruction are effective and what makes them most effective has grown…

Shadowing is the act of vocalizing the speech one is listening to as simultaneously as possible. The primary function of shadowing is learners' listening skill and pronunciation skill development. Despite the importance of second language (L2) listening skills, this pedagogical technique has not received focal attention in the field. In this…

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…

With the rise of different English varieties, scholars argued for reconceptualizing teaching pedagogies to acknowledge and incorporate diverse Global English (GE) varieties into the classroom (Rose & Galloway, 2019). However, very few studies explored the effectiveness of such innovative pedagogy on language skills. This study investigated the…

Research on intelligibility in international encounters has long focused on issues of pronunciation to the detriment of factors such as linguistic co-text and extralinguistic context, which are comparatively well-studied variables in intelligibility research concerning L1 listeners. This paper seeks to expand the scope of international…

Automatic Speech Scoring (ASS) has increasingly become a useful tool in oral proficiency testing for Second Language (L2) learners. However, limited studies investigate the alignment of ASS indices with the Complexity, Accuracy, and Fluency (CAF)--the three dimensions in evaluating L2 speakers' oral proficiency, and the subsequent impact indices…

This study examines the second language (L2) development of variable /s/-weakening in the spontaneous speech of L2 learners of Spanish who studied abroad in either Dominican Republic, where /s/-weakening is widespread, or central Spain, where /s/-weakening is much less common. Learners' realizations of /s/ were coded impressionistically and…

Despite the fact that pronunciation is a vital aspect of language learning, previous research has shown that its instruction is limited in the classroom in terms of time and attention, due in part to the time constraints inherent in any curriculum. It then becomes essential for instructors to be strategic about the pronunciation features they…

Educational speaking technology is a digital expertise used to enhance speaking performance. This research examined the effects of using educational speaking technology tools: FORVO, YouGlish, and OALD 8th ed. to enhance students' speaking performance. A quasi-experimental pretest-posttest two groups design was used. Test, questionnaire,…

This paper provides a research synthesis of intelligent personal assistants (IPAs) -- that is, cloud-based virtual assistants such as Alexa, Google Assistant, and Siri -- for second language (L2) learning. The article also offers a theoretical justification for the use of IPAs in language learning and outlines the affordances and constraints of…

Our study proposes the use of a free classification task for investigating the dimensions used by listeners in their perception of nonnative sounds and for predicting the perceptual discriminability of nonnative contrasts. In a free classification task, participants freely group auditory stimuli based on their perceived similarity. The results can…

Phonetic imitation is a ubiquitous process in speech production. Speakers have a strong tendency to imitate their interlocutors both in a native and a non-native language. It is especially important in acquiring non-native speech, because it allows forming new sound categories. In the current study we investigated whether and to what extent Polish…

This study aims to investigate the VOT values of English wordinitial plosive consonants produced by young Thai learners to understand current trends in English pronunciation among Thai speakers and its future direction. The study analyzes how phonological mismatches between Thai and English affect the pronunciation of Thai learners, using a speech…

Rhythm metrics can detect second language development of target-like speech rhythm but interpretation of the results from metrics in learners' speech is problematic because the mapping of metrics to underpinning phonological features is indirect. We investigate speech rhythm in first language (L1) Arabic / second language (L2) English, which…

This study investigates acoustically one of long-term debated phonetic characteristics, the so-called Arabic voiced pharyngeal fricative /[voiced pharyngeal fricative]/. Most recent studies have found the Arabic pharyngeal to be approximant, while others have categorized it as a stop in careful speech, and still others have suggested it is a…
