Understanding Dutch AU files
Netherlands Dutch and Belgian Dutch (Flemish) share one written standard but sound noticeably different — Flemish is spoken with a softer "g" and uses more French-influenced vocabulary. Surinamese Dutch and regional accents like Brabantian add further pronunciation differences, though all are handled as accents of the same Dutch language. Limburgish, by contrast, is officially recognized as a distinct regional language in the Netherlands, so treat it separately from accented standard Dutch.

Frequently asked questions
How to improve the accuracy of your Dutch transcripts?
Start by improving the quality of the Dutch AU 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 Dutch AU file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Dutch AU file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AU, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Dutch with Sonix:
Why is my Audacity project folder full of small AU files?
Older versions of Audacity split a project's audio into small AU block files inside a _data folder so long tracks could be edited efficiently, and the .aup project file reassembles them in order. Avoid moving or renaming these chunks; open the project and export the audio instead.
How do I play a standalone AU file?
Standalone AU files use the Sun audio format and open in players such as VLC and editors such as Audacity. Converting to WAV or MP3 gives the broadest compatibility with modern software and devices.
Can Sonix transcribe Flemish (Belgian Dutch)?
Yes. Flemish shares the same written standard as Netherlands Dutch, so Belgian Dutch audio is transcribed with the Dutch language model, and you can adjust regional vocabulary in the transcript editor before exporting.
Is Afrikaans the same as Dutch for transcription?
No. Afrikaans evolved from Dutch but is a distinct language, so choose the language setting that matches your audio rather than treating the two as interchangeable.
Does Dutch transcription handle English words mixed into speech?
Dutch speakers often mix English terms into business and tech conversations, and those loanwords may need light cleanup, which you can do in the built-in editor after the automated transcript is ready.

I have to say the Arabic transcription was pretty awesome.
I have absolute admiration for the impressive transcription done to 3 short YouTube videos. It is truly amazing how accurately it recorded the correct words and so well paragraphed as well.
