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…

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 article considers the construct of fluency in second language assessment and how it might be informed by research in applied linguistics. It briefly describes the way fluency is conceptualized in four language tests, as embodied in their respective assessment criteria, to show where the field is at present. The article then takes into account…

In vocabulary research there has been a shift from focusing on single words to considering multiword sequences, such as collocations. Despite the general consensus among language researchers that collocation is essential to effective language use in real-world communication, particularly oral communication, language-testing researchers have made…

Examining spoken features across proficiency levels allows researchers to explore the nature of speaking proficiency as it develops. This line of research has thus far primarily focused on adult second language (L2) learners. Using cross-sectional data based on a large-scale language assessment intended for young L2 learners, in this study, we…

This study determines the fine-grained bottom-up linguistic features involved in successful second language (L2) English academic group oral tutorial discussion through the use of a spoken learner corpus composed of more than 20 hrs of L2 production. Student performances were graded by teacher-raters using a can-do rating scale, which assessed…

In the present study we investigated the effect of test format on oral performance in terms of test scores and discourse features (accuracy, fluency, and complexity). Moreover, we explored how the scores obtained on different test formats relate to such features. To this end, 23 Iranian EFL learners participated in three test formats of monologue,…
