Feedback in an ASR-based CALL system for L2 syntax: a feasibility study
نویسندگان
چکیده
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 and tested a CALL system in a pilot experiment. This paper analyses the accuracy of the feedback in the system, showing that it performs accurately. We also provide an overview of learner behaviour in the exercises, with a view to understanding how learners respond to feedback, and to system errors. Based on our analysis, we suggest ways of improving the feedback that might increase training effectiveness without exceeding the limits of the ASR technology.

DISCO: 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...

In this paper we describe the language resources developed within the project “Feedback and the Acquisition of Syntax in Oral Proficiency” (FASOP), which is aimed at investigating the effectiveness of various forms of practice and feedback on the acquisition of syntax in second language (L2) oral proficiency, as well as their interplay with learner characteristics such as education level, learn...
متن کاملThe Role of Corrective Feedback in Second Language Learning: New Research Possibilities by Combining CALL and Speech Technology
The role of corrective feedback (CF) is debated in second language acquisition (SLA). It has not been unequivocally shown that CF is effective in SLA, in particular not in the case of on-line processing, as in oral second language (L2) proficiency. This might be because, to date, it has not been feasible to create appropriate research conditions. We claim that these problems can be alleviated b...

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 کاملEffective feedback on L2 pronunciation in ASR-based CALL
Computer Assisted Language Learning (CALL) has now established itself as a prolific area whose advantages are well-known to educators. Yet, many authors lament the lack of a reliable integrated conceptual framework linking technology advances and second language acquisition research within which effective materials can be designed [1],[2]. The CALL world has recently witnessed a flourishing of ...
