The Nordic Dialect Corpus project was initiated by the Scandinavian Dialect Syntax Network (ScanDiaSyn). In order to be able to study the North Germanic (i.e., Nordic) dialects, proper documentation of the dialects was needed. A corpus consisting of natural speech by dialect speakers was developed in order to systematically map and study syntactic variations across the Scandinavian dialect continuum. The corpus was to be comprised of transcribed and tagged speech material linked to audio and video recordings. Further, it was decided that a user-friendly interface should be developed for the corpus, and that it should be available on-line. The corpus is now ready for use, and is described here.
