A key challenge in developing speech-enabled CALL systems is to design for more linguistic-didactic functionality while remaining within the limits of technological feasibility.This especially applies to systems intended for practicing grammar.This presentation describes the DISCO system, which makes use of automatic speech recognition (ASR) to provide feedback on grammar and pronunciation of Dutch L2.We will also focus on the requirements for goal-oriented design and implementation of speech technology.On the one hand we are developing and testing speech technology modules to determine what is feasible.On the other we use this knowledge in the goal-oriented, ecological and ontological design of a CALL system for practicing pronunciation and grammar.
