16 March 2021
Doctoral research project at KU Leuven and UCLouvain. Funded by a SENESCYT scholarship (Ecuador).
Focused on the design and evaluation of task-based dialogue systems (chatbots, conversational agents…) for language learning.
Researcher: Serge Bibauw.
Supervisors: Piet Desmet (itec, KU Leuven) and Thomas François (CENTAL/TeAMM, UCLouvain)

We propose a common definition for dialogue-based CALL and establish a first overview of the literature in the domain, from a systematic literature review of 138 papers. Results show a scattered research field, with 4 main disciplinary approaches, each preferring a certain keyword for referring to the domain.

Abstract
BACKGROUND. Interactivity has been defined in various ways: in instructed SLA, as distinguishing dialogic tasks from monologic ones (Ellis et al., 1994); in game design, as involving agency and user control.

Abstract
The number of times a word appears in the input, i.e., the frequency of occurrence, is a well-known factor influencing incidental vocabulary acquisition (Webb, 2020). However, paradoxically, the frequency of occurrence has only a medium predicting power in vocabulary learning, around r = .

Las inteligencias artificiales conversacionales—es decir, los chatbots, los robots parlantes, los agentes conversacionales y los sistemas de diálogo—ofrecen una posibilidad prometedora para el aprendizaje de idiomas: un entorno de baja ansiedad para la práctica comunicativa e interactiva, que puede además controlarse en cuanto a complejidad y exposición específica, estrategias de andamiaje y retroalimentación correctiva.

Automatizing testing and computation of multiple variations (pruning, normalization…) of L2 utterance fluency metrics, we collected pre/post oral interview responses from N=215 learners of French, and compared each metric’s variation with external proficiency estimates, to determine which operationalizations best predict proficiency and detect very-short-term developmental changes in L2 fluency.

Introduction Dialogue-based computer-assisted language learning (CALL) allows a learner to practice an L2 by discussing with a computer. By offering a fully controllable meaning-focused learning environment, it also allows investigating the effectiveness of different modalities of interaction (Bibauw et al, 2019).

Chatbots and conversational agents have recently seen major developments in many domains, including education. In foreign language learning, dialogue-based computer-assisted language learning (CALL) applications allow a learner to practice a foreign language by having a conversation with a computer, be it orally or in writing.
