Abstract

This paper presents an ICALL system for learning complex inflection systems; based upon finite state transducers (FST). Using a FST has several advantages: it makes it possible to generate a virtually unlimited set of exercises with a relatively small amount of work; and it makes it possible to process both input and output according to a wide range of parameters; such as dialect variation; and varying writing conventions. It also makes it possible to anticipate common error types; and give precise feedback both on errors and possible corrections. It shifts the developer’s focus from form generation and over to a pedagogically-motivated modelling of the learning task. The system is in active use on the web for two Saami languages; but can be made to work for any inflectional language.
