Understanding Norwegian OPUS files
Norwegian has two official written standards, Bokmål and Nynorsk, but no single standard spoken form — regional dialects from Oslo, Bergen, Trøndelag, and northern Norway differ noticeably in pronunciation, intonation, and vocabulary, and are used freely in broadcasting and formal settings. Automated transcription typically renders speech in Bokmål-style written Norwegian regardless of the speaker's dialect.

Frequently asked questions
How to improve the accuracy of your Norwegian transcripts?
Start by improving the quality of the Norwegian OPUS file that you upload to Sonix. Please use high quality recording equipment, recording in a quiet environment, and ensure that your speakers are speaking clearly to ensure that your transcript is as accurate as possible.
Any advice for the Norwegian OPUS file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Norwegian OPUS file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from OPUS, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Norwegian with Sonix:
Why won't my OPUS file play on my computer?
Older media players and some built-in OS players lack Opus support. Opening the file in VLC or a modern web browser, or converting it to MP3 or WAV, usually resolves the issue.
Are WhatsApp voice messages OPUS files?
Yes, WhatsApp exports voice notes as .opus files. You can upload them for transcription directly without converting them first.
Does Sonix transcribe Norwegian in Bokmål or Nynorsk?
Automated Norwegian transcripts generally follow Bokmål written conventions, since Bokmål is the more widely used written standard. You can edit the transcript into Nynorsk in the Sonix editor before exporting.
Can Sonix handle Norwegian dialects like Bergen Norwegian or Trøndersk?
Yes — you upload your audio, Sonix transcribes it, and you can correct any dialect-specific passages in the editor. Speech closer to standard Eastern Norwegian typically needs fewer corrections than heavier regional dialects.
Should I choose Norwegian or Danish for my Scandinavian audio?
Choose the language actually being spoken. Written Norwegian and Danish look similar, but their pronunciation differs substantially, so selecting the correct language gives the speech model the right acoustic match.
