Language learners are known to fare best in one-on-one interactive learning situations in which they receive optimal corrective feedback. However, providing this type of tutoring by trained language instructors is time-consuming and costly, and therefore not feasible for the majority of language learners. This particularly applies to oral proficiency, where corrective feedback has to be provided immediately after the utterance has been spoken, thus making it even more difficult to provide sufficient practice in the classroom. The recent appearance of Computer Assisted Language Learning (CALL) systems that make use of Automatic Speech Recognition (ASR) and other advanced automatic techniques offers new perspectives for training oral proficiency in a second language (L2).
The present project aims to develop and test a prototype of an ASR-based CALL application for training oral proficiency for Dutch as a second language (DL2). The application optimizes learning through interaction in realistic communication situations and provides intelligent feedback on various aspects of DL2 speaking, viz. pronunciation, morphology and syntax. The communicative settings employed in Nieuwe Buren (New Neighbours, a method for DL2 training developed by Malmberg publishers) will constitute the starting point for the application.
This project addresses the STEVIN priorities, tools and data for the development of CALL applications, educational system, robustness of speech recognition, confidence measures and adaptation. It combines speech and language technology techniques to form a state-of-the-art CALL application, which can be considered innovative from an international perspective.
The results of this project are relevant for companies and institutions that conduct research and develop applications in educational speech and language technology, and also for publishers.
This project will be carried out within the framework of the Stevin Program.
