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 complete system.
