Norwegian Speech Recognition Acoustic Database

This database was created by Nordic Language Technology for developing automatic speech recognition and dictation systems for Norwegian. The data was preserved and transferred to the National Library of Norway's Språkbanken in 2011.

Use Cases

• Train acoustic models for Norwegian automatic speech recognition using the provided acoustic data.
• Develop dictation systems for the Norwegian language based on the acoustic databases.
• Research phonetic and acoustic properties of Norwegian speech from the preserved recordings.

Strengths

• Created by a dedicated language technology firm (Nordisk språkteknologi holding AS) for ASR development.
• Preserved and made available by a national institution (National Library of Norway) ensuring long-term access.
• Open to user feedback and improved versions for community-driven enhancement.

Limitations

• The original data collection ended with the firm's bankruptcy in 2003, potentially limiting recency.
• The data organization has been altered from its original form, which may affect compatibility with older documentation.
• Specific details on data size, format, and recording conditions are not provided in the description.
