Dr Lilia Moskalenko from the Institute of Ukrainian Language of the National Academy of Sciences of Ukraine came last summer for two months as a DAAD scholarship to the sound archive (Lautarchiv) of the Humboldt-Universität zu Berlin, which contains recordings in about 250 languages. She has studied unique archived 45 Ukrainian recordings and the corresponding documents. These recordings originate from war prison camps of the First World War, where Berlin scientists recorded the various mother tongue languages of the war prisoners (the ethics of this research is a separate issue, which needs to be addressed by experts). It requires special linguistic knowledge to classify the different dialects, which might no longer exist, and Lilia Moskalenko brought her profound experience in the exploration of Ukrainian dialects. The value of these recordings is difficult to overestimate, since there are apparently no voice recordings of spoken Ukrainian from the early 20th century in Ukraine.
