+## Dataset Creation
+
+### Curation Rationale
+
+There are not many large-scale ASR datasets in Danish.
+
+### Source Data
+
+The data originates from the now bankrupt company Nordisk språkteknologi (NST), whose data was transferred to the National Library of Norway, who subsequently released it into the public domain.
+
+
+## Additional Information
+
+### Dataset Curators
+
+[Dan Saattrup Nielsen](https://saattrupdan.github.io/) from the [The Alexandra
+Institute](https://alexandra.dk/) reorganised the dataset and uploaded it to the Hugging Face Hub.
