The work related to Endangered Languages and Endangered Archives at the Fryske Akademy and the Mercator European Research Centre is focused on the study of language contact and language change and the reconstruction of historical sound recordings. We investigate the phonetic aspects of languages and dialects of minority and regional languages, in particular those of the Russian Federation and neighbouring countries. Various projects have been supported by grants from the Netherlands Organisation for Scientific Research (NWO), the Organisation INTAS of the European Union, the British Library, Japanese Foundations and Sakhalin Energy Investment Company Ltd.
