ISCA International Workshop on Speech and Language Technology in Education (SLaTE 2011)
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.
