The goal of a recently concluded project in Switzerland was to pioneer an assessment system for lexical signs of Swiss German Sign Language (Deutschschweizerische Gebärdensprache, DSGS) that relies on automatic sign language recognition. The assessment system gives adult L2 learners of DSGS feedback on the correctness of the manual parameters of signing (handshape, hand position, location, and movement) of isolated signs they produce. In its initial version, the system includes automatic feedback for a subset of a DSGS vocabulary size production test consisting of approximately 100 lexical items at CEFR level A1. The paper at hand reports on the process of selecting the items for the test, compiling training data for the SLR system, and linguistically analyzing errors in the resulting video recordings.
