We report a preliminary version of a database from which examples of historical sound change can be retrieved and analyzed. To date, the database contains about 1,000 examples of regular sound changes from a variety of language families. As exemplified in the text, searches can be made based on IPA symbols, articulatory features, segmental or prosodic context, or type of change. The database is meant to provide an adequately large sample of areally and genetically balanced information on historical sound changes that tend to take place in the world’s languages. It is also meant as a research tool in the quest for diachronic explanations of genetic and areal biases in synchronic typology.
