Corpus-based studies have offered the domain definition inference for test developers. Yet, corpus-based studies on temporal fluency measures (e.g., speech rate) have been limited, especially in the context of academic lecture settings. This made it difficult for test developers to sample representative fluency features to create authentic…

Fluency in terms of speed of speech and (lack of) hesitations such as silent and filled pauses ('uhm's) is part of oral proficiency. Language assessment rubrics therefore include aspects of fluency. Measuring fluency, however, is highly time-consuming because of the manual labour involved. The current paper aims to automatically measure aspects of…

The present study investigates the efficacy of preparation time in four speaking tasks of TOEFL iBT. As the current pre-task planning time offered by ETS is very short, 15 to 30 seconds, we intended to explore how the test-takers' speaking quality would change if the preparation time was added to the response time, giving the respondents a…

This study attempted to check the impact of two dynamic assessment (DA) models on speaking CAF. DA, as opposed to static assessment, is conceived as an interactive approach to assessment that integrates teaching and testing into a unified instructional engagement. To achieve the goals of this research, a convenience sample of 90 upper-intermediate…

A challenge of large-scale oral communication assessments is to feasibly assess a broad construct that includes interactional competence. One possible approach in addressing this challenge is to use a spoken dialog system (SDS), with the computer acting as a peer to elicit a ratable speech sample. With this aim, an SDS was built and four trained…

The rating of proficiency tests that use the Inter-agency Roundtable (ILR) and American Council on the Teaching of Foreign Languages (ACTFL) guidelines claims that each major level is based on hierarchal linguistic functions that require mastery of multidimensional traits in such a way that each level subsumes the levels beneath it. These…

This study investigated U.S. undergraduates' perceptions of non-native speakers' (NNS) speech which had received 100% proficiency scores on the TOEFL iBT test. Fifty-five U.S. undergraduates rated 20 speech samples for comprehensibility, accentedness, and acceptability. The speech samples were also analyzed for acoustic fluency. Descriptively,…

The present study investigated the speaking module of TOEFL iBT with an emphasis on the dichotomy of independent and integrated tasks. The potential differences between the two speaking conditions were intended to be explored based on the oral performance elicited from a group of Iranian test takers. To collect the required data, a simulated…

Research examining test taker fluency in simulated and face-to-face oral proficiency interview performances has primarily focused on quantitative spoken utterance fluency data alone, with further qualitative investigation of test taker processing fluency's effect being neglected. This study compared four test takers' spoken utterance and…

The current paper examined the impact of Dynamic Assessment (DA) on the speaking skills of EFL learners applying socio-cultural theory, which was developed by Vygotsky (1934). The study also tried to compare the results from online synchronous DA sessions, which were done in the form of one-to-one online training over Google Meet, with the results…

The literature on task planning abounds with studies in laboratory or classroom contexts; however, the contribution of task planning to the testing context has remained a largely uncharted area of enquiry. The current study is primarily focused on exploring the impacts of pressured vs. unpressured on-line task planning conditions on EFL students'…

Where the veracity of a statement is in question, listeners tend to interpret disfluency as signaling dishonesty. Previous research in deception suggests that this results from a speaker model, linking lying to cognitive effort and effort to disfluency. However, the disfluency-lying bias occurs very quickly: Might listeners instead simply…

While fluency in second language speaking can be a challenging construct to measure, it is important to identify the discourse features that contribute to it. This small-scale classroom research project examined the effect of formulaic language sequences on fluency as measured by computer-based speaking tasks of young English learners. Thirty-six…

The Vodcasting technology has thrived as an auxiliary tool to support learners with supplementary materials. The current study aimed at exploring the use of vodcasting technology and the learners' perceptions and attitudes towards practicing L2 vodcasting tasks. For this reason, a sample of 120 Iranian EFL learners were selected and they received…

The present study investigates integrated writing assessment performances with regard to the linguistic features of complexity, accuracy, and fluency (CAF). Given the increasing presence of integrated tasks in large-scale and classroom assessments, validity evidence is needed for the claim that their scores reflect targeted language abilities.…
