This is a web interface for Kondien Koltosva, a toolkit for statistical machine translation. It is still in progress and actual sentence translation is not implemented yet. You can however query for individual word translations, gathered from a rather limited set of Finnish and Karelian parallel corpora.
Note that, in contrast to e.g. the KKS Karjalan Kielen Sanakirja hosted by Kotus (which was manually assembled from field-work data and tries to cover many varieties), this dictionary is automatically generated from parallel texts in original Finnish and translated Olonets Karelian (Livvi).
