The revised Speech Learning Model (SLM-r) postulates that learners with more precisely defined categories in their native language (L1) exhibit greater proficiency in acquiring sounds in a second language (L2). Despite its recent emergence, empirical studies validating this hypothesis remain scarce. This study aims to investigate the predictive…

Background: While automatic speech recognition (ASR) is increasingly used for commercial purposes, its influence on the learners' linguistic performance in terms of oral complexity, accuracy and fluency was under-explored. To date, few studies have been conducted to investigate how the dictation ASR technology could be incorporated into language…

Previous research has shown that task repetition can positively affect L2 oral performance. However, few studies have explored the effects of task repetition on young EFL learners' production. Also, task repetition research has paid little attention to effects of "spacing" examined through longer time intervals between the two occasions…

Language learning activities involving time-pressured repetition of similar content have been shown to facilitate improvements in fluency. However, concerns have been voiced about whether these gains might be offset by reduced levels of grammatical accuracy. This descriptive study tracked the oral proficiency of 32 Japanese university students…

Language testing research has suggested that placement accuracy can be an important factor in the consequences of placement decision-making. However, previous studies primarily have used a one-shot teacher judgment of placement accuracy, suffering from a lack of students' perspectives of their time-varying experiences. The present study aimed to…

In this study, I compare the accuracy of automatic speech recognition (ASR) transcription against two measures of intelligibility provided by human listeners. The data came from readings of five texts recorded by 15 language learners of French. Human understanding was gauged by (i) asking a group of 36 naïve first language (L1) speakers of French…

This longitudinal study made the first attempt to employ Latent Growth Curve Modeling to analyze the development of L2 speaking accuracy and fluency through online scaffolding as well as the dynamic relationship between L2 speaking performance and self-efficacy. From the perspective of Complex Dynamic Systems Theory, it tracked the development of…

This research investigates the use of artificial intelligence (AI) tools by Indonesian EFL learners to enhance their presentation skills through self-regulated learning. With the rapid advancement of AI technologies, their integration into educational practices has become increasingly significant, particularly in developing essential skills like…

The effects of learner- and task-related variables on second language (L2) writing syntactic complexity (SC) have been extensively investigated. However, previous research has rarely assessed the reliability of computational tools for analyzing the SC of L2 spoken production, and we know less about the effects of such variables on L2 speaking SC.…

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…

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…

This study aims to investigate the effectiveness of explicit formal instruction (EFI) on speaking and pronunciation skills among a Kurdish university's first-year EFL students. The researcher was teaching a communications unit, where the focus was on speaking skills and pronunciation: speech rate (words per minute), fluency (number of pauses and…

Learners' anxiety has drawn widespread attention in the field of second language/foreign language (L2/FL) teaching and learning (e.g. classroom anxiety, communication (with foreigners) anxiety, and anxiety associated with the four macro-skills, namely listening, reading, speaking, and writing). However, this topic is under-explored in L2/FL public…

"How can teachers help students improve their second language (L2) speaking accuracy?" This is a question that most L2 educators ask themselves every day. Although L2 writing is a popular topic among Second Language Acquisition (SLA) researchers, the consideration that L2 writing has the potential to act as a scaffold for L2 speaking…

This study investigates the differential effects of a task-based inside-school intervention and an outside-school project intervention on the development of speaking skills of 56 beginner second language (L2)-learners. The study extends previous research by looking at development across multiple occasions instead of two (i.e., a pretest and…
