The importance of vocabulary when speaking is not only demonstrated in models of second language speech production and speaking proficiency but also reflected in rating criteria and assessment scales. The present study examined and compared micro-level lexical information in a speaking task from two complementary stakeholders' perspectives…

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…

Purpose: Bilingual children's speech often contains high percentages of disfluencies in both their languages; however, the distribution of disfluency types and the difference across bilinguals' two languages have received insufficient and inconsistent empirical support. The present research aims to profile "typical" bilingual disfluency…

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…

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 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…

The main aim of this study was to investigate how oral fluency is assessed across different levels of proficiency in the Test of English for Educational Purposes (TEEP). Working with data from 56 test-takers performing a monologic task at a range of proficiency levels (equivalent to approximately levels 5.0, 5.5, 6.5, and 7.5 in the IELTS scoring…

This research aimed to: (1) develop a task-based Chinese speaking (TBCS) instructional model to enhance the Chinese speaking skills of beginner-level Thai learners studying Chinese as a foreign language (CFL), (2) implement the developed TBCS instructional model with beginner-level Thai CFL learners for refinement, and (3) evaluate the suitability…

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…
