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…

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…

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…

This paper explores what the measures of utterance fluency typically employed in Automatic Speech Evaluation (ASE), i.e. automated speaking assessments, tell us about oral proficiency. 60 Chinese learners of English completed the second part of the speaking section of IELTS and six tasks designed to measure the linguistic knowledge and processing…

This longitudinal study examines the effects of a pre-study abroad (SA) pedagogic intervention and subsequent SA experience on second language (L2) Mandarin fluency. It explores two temporal aspects of oral fluency--planning time and speech rate--along with one performance measure, duration of response. Additionally, L2 contact data were included…

Though there is an urgent need to improve Thai graduates' ability to speak English fluently, very few studies have focused on students' fluency in language teaching in Thailand. The study investigated 86 third-year university students' beliefs regarding English-speaking fluency, including the characteristics and importance of fluency and the…

The present study investigated the potential of writing in English as a foreign language (EFL) for language learning by manipulating cognitive task complexity based on related models and hypotheses. English essays written by 59 Chinese postgraduate EFL students from different subject areas were analysed with reference to writing complexity,…

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…

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…

Dynamic assessment has been proven to effectively promote EFL learners' speaking proficiency, but its implementation in teaching speaking skills has been limited. One of the main reasons is that, thus far, very few studies have scrutinized the impacts of its two main models, interactionist and interventionist, on the speaking sub-skills of EFL…

Second language (L2) learners hold different learning beliefs that influence their interpretation of classroom experiences and their L2 learning process. Developing a thorough understanding of such beliefs is therefore imperative. This article reports the representations of Iranian English-as-a-foreign-language (EFL) learners' beliefs about L2…

This paper examines the implications of the association patterns in our understanding of the mental lexicon. By applying the principles of graph theory to word association data, we intend to explore which measures tap better into lexical knowledge. To that end, we had different groups of English as Foreign language learners complete a lexical…

In recent years, there has been growing interest in the use of data-driven learning (DDL) in L2 writing instruction. This paper examined whether and to what extent DDL activities could enhance the writing complexity, accuracy, and fluency (CAF) of 30 Thai EFL learners. The presentation of DDL in this study was hands-on concordancing with the…

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'…
