The DISCO ASR-based CALL system: practicing L2 oral skills and beyond
نویسندگان
چکیده
In this paper we describe the research that was carried out and the resources that were developed within the DISCO (Development and Integration of Speech technology into COurseware for language learning) project. This project aimed at developing an ASR-based CALL system that automatically detects pronunciation and grammar errors in Dutch L2 speaking and generates appropriate, detailed feedback on the errors detected. We briefly introduce the DISCO system and present its design, architecture and speech recognition modules. We then describe a first evaluation of the complete DISCO system and present some results. The resources generated through DISCO are subsequently described together with possible ways of efficiently generating additional resources in the future.

Practice and feedback in L2 speaking: an evaluation of the DISCO CALL system
In this paper we report on the ASR-based CALL system DISCO: Development and Integration of Speech technology into COurseware for language learning. The DISCO system automatically detects pronunciation and grammar errors in Dutch L2 speaking and generates appropriate, detailed feedback on the errors detected. We briefly introduce DISCO and present the results of a first evaluation of the complet...
متن کاملDISCO: development and integration of speech technology into courseware for language learning
Recent research has shown that a properly designed ASRbased CALL system (Dutch-CAPT) was capable of detecting pronunciation errors and of providing comprehensible feedback on pronunciation. Since pronunciation is not the only skill required for speaking a second language, we explored the possibility of extending the Dutch-CAPT approach to other aspects of speaking proficiency like morphology an...
متن کاملFeedback in an ASR-based CALL system for L2 syntax: a feasibility study
In the FASOP project, we are interested in using CALL systems to study issues in foreign language learning, particularly those related to the acquisition of spoken proficiency. Specifically, we use ASR in a CALL system that provides oral practice exercises to investigate the role of corrective feedback in syntax acquisition of Dutch L2. To investigate the feasibility of this proposal we built a...
متن کاملIranian EFL Learners’ Autonomous Behavior in Out-of-class Contexts: A Call for Understanding Learners’ Personalized Approaches to Learning
The salient, and often ignored, role that out-of-class learning plays in second/foreign language (L2) learners’ development is overshadowed by classroom research. The main aim of this study is to problematize the role of out-of-class learning in the specific English-as-Foreign-Language (EFL) context of Iran by examination of the ways in which four learners attempted to revamp their English lang...
متن کاملSpoken grammar practice in an ASR-based CALL system
In this paper we present a computer assisted language learning (CALL) system that is developed to practice grammar in spoken language. To enable this, the system uses Automatic Speech Recognition (ASR) to process the L2 learner’s responses. We investigate the possibility of providing corrective feedback (CF) on learner errors, and compare that with self-monitored language learning through outpu...
