This study is the first attempt to explore the relationship between rater variables focusing on raters' language aptitude and their judgments of second language (L2) speech. Thirty-four English listeners rated 65 spontaneous native and nonnative speech samples for comprehensibility, accentedness, and fluency. They also completed the LLAMA language…

This study explored two assessment approaches to oral performances: analytical complexity, accuracy, and fluency (CAF) indices and human raters' evaluations. CAF indices are frequently used in second-language speaking (L2) research; however, because tasks are communicative and goal-oriented, the degree to which students achieve such communicative…

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…

Nonverbal behavior can impact language proficiency scores in speaking tests, but there is little empirical information of the size or consistency of its effects or whether language proficiency may be a moderating variable. In this study, 100 novice raters watched and scored 30 recordings of test takers taking an international, high stakes…

This study compared holistic and analytic marking methods for their effects on parameter estimation (of examinees, raters, and items) and rater cognition in assessing speech act production in L2 Chinese. Seventy American learners of Chinese completed an oral Discourse Completion Test assessing requests and refusals. Four first-language (L1)…

It is general practice to use rater judgments in speaking proficiency testing. However, it has been shown that raters' knowledge and experience may influence their ratings, both in terms of leniency and varied focus on different aspects of speech. The purpose of this study is to identify raters' relative responsiveness to fluency and linguistic…

This study examined the impact of the manipulated task complexity (Robinson 2001a, 2001b, 2007, 2011; Robinson & Gilabert, 2007) on second language (L2) speech comprehensibility. I examined whether manipulated task complexity (a) impacts L2 speech comprehensibility, (b) aligns with L2 speakers' perception of task difficulty (cognitive…

Many studies that have investigated the educational value of online machine translation (MT) in second language (L2) writing generally report significant improvements after MT use, but no study as of yet has comprehensively analyzed the effectiveness of MT use in terms of various measures in syntactic complexity, accuracy, lexical complexity, and…

Despite the benefits of performance-based oral communication tests, a plethora of variables, as illustrated in Ockey and Li's (2015) model of oral communication assessment, can create construct-irrelevant variance in test scores. In relation to human participants in the oral communication tests, previous studies mostly focused on the direct effect…

This study compares the language proficiency gains of two groups of students taking a business English course module in a bilingual university in Catalonia (Spain). Whereas one of these groups followed a 'translanguaging' or 'plurilingual' pedagogy, the other followed a strictly monolingual approach. Participants were 54 mostly Catalan/Spanish…

Summative assessment of interpretation is widely conducted in interpreting courses/programs to inform high-stakes decision making, such as the selection, certification, and conferral of academic degrees. Yet there has been very limited empirical research to investigate the score dependability of summative interpretation assessment. The present…

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,…

The current study longitudinally examined the influence of aptitude on second language (L2) pronunciation development when 40 first-year Japanese university students engaged in practice activities inside and outside English-as-a-Foreign-Language classrooms over one academic year. Spontaneous speech samples were elicited at the beginning, middle,…
