Welcome to


This web site provides interactive visualisations of Swiss German dialect maps.

Digitized dialect maps

A selection of dialect maps published in the Sprachatlas der deutschen Schweiz (SDS) was digitized by Yves Scherrer and Sandra Kellerhals. The menu item Digitized dialect maps provides access to an interactive map viewer and to downloads of the data sets in different formats.

The website www.sprachatlas.ch (in German) lists a wealth of background information and original data material on the SDS project.


In collaboration with the Salzburg dialectometry group around Prof. Hans Goebl, various dialectometric visualisations were created on the basis of the digitized maps. These visualisations can be consulted under the menu item Dialectometry.

NEW (2020): Dialectometric visualisations are now also available for the British English and various Romance dialect areas, in collaboration with Prof. Hans Goebl.

Translation and generation

The digitized SDS maps are also used to parameterize a machine translation system from Standard German to Swiss German dialects, and to create a dialect identification system. Such computational applications are described in Yves Scherrer's dissertation. Demos of these tools are available under the menu item Translation and generation.
