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…

This paper reports on the impact of an English as a Second Language (ESL) speaking activity--"the poster carousel"--on English learners' second language (L2) fluency. Two versions of the poster carousel were developed to observe the effect of talking about (a) the same poster three times (same-task repetition) or (b) three different…

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…

We examined the naturalistic pronunciation development of two groups of L2 speakers over 10 years. Initially, 50 beginner ESL students participated in production tasks; despite attrition, the tasks were administered eight more times. Here we report listener judgements of accentedness, comprehensibility and fluency for the remaining six Mandarin…

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…

Second language (L2) learners stand to gain substantially from mastering a wide range of multiword expressions (MWEs), and several studies have examined the benefits of language courses that regularly draw learners' attention to MWEs. However, most of these studies focused on the learners' retention of the MWEs included in the course materials and…

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…

Complexity, accuracy, and fluency (CAF) as measures of language proficiency have been used extensively in assessing second language production in English language studies related to task-based language teaching. The present review adds the following critical elements to the existing body of literature: (i) Provides synthesis and critical analysis…

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,…
