NST Norwegian ASR Database (16 kHz) - Reorganized

This database was created by Nordic Language Technology for the development of automatic speech recognition and dictation in Norwegian. In this version (from 2022), the organization of the data has been altered to make the database more user friendly.

The data set was reviewed again in December 2023; duplicates were removed, metadata was cleaned up and filenames were standardized. See the documentation file for details.

In the original version of the material, the files were organized in a specific folder structure where the folder names were meaningful. However, the file names were not meaningful, and there were also cases of files with identical names in different folders. This proved to be impractical, since users had to keep the original folder structure in order to use the data.

The files have been renamed, such that each file name is unique and meaningful regardless of the folder structure. The original metadata files were in spl format; these have been converted to JSON format. The metadata files are anonymized, and the text encoding has been converted from ANSI to UTF-8. Metadata and transcriptions are also available as CSV files.

See the documentation file for a full description of the data and the changes that have been made to the database.

本数据库由北欧语言技术（Nordic Language Technology）公司为挪威语自动语音识别与听写功能的开发所创建。在2022年发布的该版本中，为提升数据库的易用性，对数据的组织结构进行了优化调整。

该数据集于2023年12月完成新一轮审核：已移除重复文件、清理元数据（metadata）并统一文件名格式。详细信息请参阅说明文档。

在该数据集的原始版本中，文件按照特定文件夹结构组织，文件夹名称具备明确语义，但文件名无实际含义，且不同文件夹内存在文件名重复的情况。由于用户必须保留原始文件夹结构方可使用数据，该设计被证实实用性不足。

目前已对所有文件进行重命名，确保无论文件夹结构如何，每个文件名均唯一且具备明确语义。原始元数据文件采用spl格式，现已全部转换为JSON格式。元数据文件已完成匿名化处理，文本编码也从ANSI转换为UTF-8。元数据与转录文本同时提供CSV格式版本。
