Schnëssen. Surveying language dynamics in Luxembourgish with a mobile research app

The mobile app Schnëssen is intended to establish a state-of-the-art
digital platform to collect data on the present-day language situation of
Luxembourgish by means of crowd-sourcing and to document and
present results to a broader public. Users can participate in a large set of
audio recordings tasks and in sociolinguistic surveys. By presenting all
audio recordings via an interactive map, participants can explore the
language variation of their language. In the first year of data collection,
around 210.000 recordings could be collected for numerous variation
phenomena from all linguistic levels and over 2800 sociolinguistic
questionnaires have been filled out. The app allowed us to compile thus
the largest systematic spoken language corpus of Luxembourgish.
