Recent research has shown that a properly designed ASR-based 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 and syntax. In this paper we explain how a number of errors in morphology and syntax that are common in spoken Dutch L2 could be addressed in an ASR-based CALL system. Finally, we present our new project in which corrective feedback will be provided on all three aspects of spoken proficiency: pronunciation, morphology and syntax.
