Oahpa! Õpi! Opiq! Developing free online programs for learning Estonian and Võro

This paper describes porting Oahpa, a set of advanced interactive language learning programs, to two new languages both of which spoken in Estonia – Estonian and Voro. Our programs offer a platform where the user can practice vocabulary and the generation of morphologically complex forms both in isolation and within sentential contexts. An overview of the Oahpa system and its two important building blocks – the morphological finite state transducer and the pedagogical lexicon – is given. The development of morphological finite state transducers for Estonian and Voro, as well as tailoring the specific transducers for pedagogical purposes are described. The adaptation of both Estonian and Voro Oahpa to the target user groups is also discussed.
