Dialogue act (DA) classification plays an important role in understanding, interpreting and modeling dialogue. Dialogue acts (DAs) represent the intended meaning of an utterance, which is associated with the illocutionary force (or the speaker's intention), such as greetings, questions, requests, statements, and agreements. In natural language…

Purpose: This study builds a new system for automatically assessing learners' speech elicited from an oral discourse completion task (DCT), and evaluates the prediction capability of the system with a view to better understanding factors deemed influential in predicting speaking proficiency scores and the pedagogical implications of the system.…

This study explores the effects of embodied prosodic training on the production of non-native French front rounded vowels (i.e. /y, ø, oe/) and the overall pronunciation proficiency. Fifty-seven Catalan learners of French practiced pronunciation in one of two conditions: one group observed hand gestures embodying prosodic features of the sentences…

When two people interact, reference presentation is shaped with the intention of supporting addressee understanding, allowing for ease of acceptance, thus minimizing overall collaborative effort. To date, analysis of such "audience design" has focused largely on adult-adult or adult-child interaction but seldom on adult-teenager…

Speech planning is a sophisticated process. In dialog, it regularly starts in overlap with an incoming turn by a conversation partner. We show that planning spoken responses in overlap with incoming turns is associated with higher processing load than planning in silence. In a dialogic experiment, participants took turns with a confederate…

This study compared Korean adult learners' English speech in dialogic and monologic tasks, measuring 57 college students' oral proficiency in terms of holistic and analytic grades. The statistical analyses were focused on two questions: (1) how much do the holistic grades of oral proficiency and analytic grades of the four linguistic features…

Often, second/foreign (L2) language learners receive little opportunity to interact orally in the target language. Interactive, conversation-based spoken dialog systems (SDSs) that use automated speech recognition and natural language processing have the potential to address this need by engaging learners in meaningful, goal-oriented speaking…

This research involved the design of a task-based dialogue system and evaluation of its learning effectiveness. Dialogue training still heavily depends on human communication with instant feedback or correction. However, it is not possible to provide a personal tutor for every English learner. With the rapid development of information technology,…

This paper explores, through the use of the observation checklist and Conversation Analysis (CA), the discourse functions elicited by the dialogic task of the Free University of Bolzano (IT) speaking test. It aims to contribute to content validation, which has been claimed to be especially relevant in paired speaking tests, where interaction is…

Research has identified a number of dimensions along which speakers modify referring expressions. The study discussed here aimed to determine and describe the actual relationship existing between these production characteristics and corresponding measures of listener comprehension. (Author/VWL)
