The NDC database contains spontaneous speech data from dialects of the North Germanic languages across all of the Nordic countries: Norway, Sweden, Denmark, The Faroe Islands and Älvdalen (recordings from Iceland and Swedish in Finland are in process). Most of the data has been gathered between 2000 and 2010 and comes from a variety of sources. The corpus is composed of spontaneous speech from interviews and conversations. No questionnaires were used during the interviews.

The data has been transcribed into written text and is enriched with PoS tags (only for Norwegian at the moment). The transcriptions are linked with audio and video files. Locations and distribution of word forms can be displayed on maps.

The corpus has been initiated under the ScanDiaSyn research network umbrella and the Nordic Centre of Excellence NORMS. The technical solutions are provided by the Text Laboratory. More information about NDC can be retrieved at http://www.tekstlab.uio.no/nota/scandiasyn/.
