Previous research has found lexical access to be related to both categorization processes, whereby concepts are grouped into different types of categories such as taxonomic, experimental and ad hoc; and to semantic fluency, which is concerned with an individual's ability to produce words related to a specific category. However, studies analyzing…

Second language (L2) utterance fluency is crucial for speaking proficiency assessment. The measurement of L2 utterance fluency relies heavily on silent pause identification. However, empirical studies establishing specific silent pause thresholds for L2 monologic speaking are scarce, and even fewer exist for L2 dialogic speaking. This study thus…

Foreign language (L2) learners' speaking proficiency is often quantified using two dimensions: intuitive human ratings and analytical, linguistic complexity, accuracy, and fluency (CAF) indices. While previous research and assessment practices have predominantly focused on either the subjective approach to L2 speaking or the objective one, it is…

This study examined the relationship between complexity, accuracy and fluency (CAF), using longitudinal data. Conducted from the perspective of complex dynamic systems theory (CDST), this research adopted four CAF general measures to track the development of five Chinese undergraduates' English speech over a 15-week period. LOWESS graphs supported…

The relationship between foreign language anxiety (FLA) and foreign language enjoyment (FLE) experienced during a creative collaborative oral English-as-a-foreign-language task, and the relationships between FLE/FLA and task speech fluency were investigated. The task was performed by mid-intermediate/high-intermediate English learners (N = 43) in…

In response to calls for an assessment tool that provides a separate performance dimension from the linguistic quality-oriented measures of complexity, accuracy, and fluency (CAF) and guided by systemic functional linguistic (SFL) theories, this study introduces a set of fine-grained objective measures of communication/content/function…

English is especially challenging for English second language (ESL) learners because of its significant cultural and societal implications. For example, idioms--multiworded expressions with multiple meanings--are problematic for ESL learners because of ambiguity in literal translation and reliance on the societal context. This quantitative…

Current L2 utterance fluency literature tends to operationalize disfluency as isolated, individual features. However, disfluency features often co-occur at one location or across multiple locations in one utterance. This study explores the co-occurrence of L2 disfluency features in a speech corpus from 71 L1 and L2 speakers of English across…

Background/purpose: Despite its informal setting, it is astonishing that the members of online English-speaking club (ESC) are adept at speaking. Employing a mixed-methods approach, more specifically a descriptive case study, this study aimed to evaluate the ESC contribution to its members' speaking competence development, to examine their…

This quasi-experimental study investigated the impacts of two instructional conditions on the fluency of learners' performance. In the first condition (strategy training), learners were provided with explicit fluency strategy training for a portion of each lesson before rehearsing versions of the speaking task for the remainder of the lesson. In…

The current study investigates whether vocabulary breadth, vocabulary depth, and vocabulary fluency contribute differentially to L2 reading and listening comprehension. One hundred and thirty-eight EFL learners first took three vocabulary knowledge tests that measured vocabulary fluency, vocabulary breadth, and vocabulary depth. Subsequently, they…

Teaching speaking skills to EFL learners remains a significant challenge, often hindered by traditional methods that prioritize rote learning over meaningful communication. This study investigates the impact of communicative language teaching (CLT) on the speaking skills of Grade 12 students, while also exploring their attitudes toward this…

Most EFL classrooms focus on building students' grammatical accuracy by learning rules and demonstrating mastery of form through exam-oriented assessments, rather than building fluency in the language by applying grammar in communication to make meaning. Moreover, grammar instruction is often rooted in materials that lack relevance to students'…

Over the past decades, language teachers have utilized the advantages of technology in the language classroom, yet given the explosion of technological tools and applications in recent years, there is no consensus as to which technological advancement best serves the development of which language skills or components. The current investigation was…

Natural Language Processing (NLP) has emerged as a transformative tool for EFL speaking instruction. However, prior research lacks robust empirical investigations into how distinct NLP tools independently enhance adaptability, accuracy, and fluency--particularly through controlled, large-scale interventions. Most studies focus on short-term…
