Understanding German AU files
Spoken German ranges from Standard German (Hochdeutsch) to strong regional varieties such as Bavarian, Low German, and Alemannic Swiss German, which can differ substantially from the standard language. Automated speech recognition is trained primarily on Standard German, so Austrian and Swiss Standard German are generally well handled while heavily dialectal speech, especially conversational Swiss German, is harder to recognize.

Frequently asked questions
How to improve the accuracy of your German transcripts?
Start by improving the quality of the German 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 German AU file that I upload?
Yes, please do not over-compress or over-filter the audio track of your German 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 German 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.
Does German transcription handle Austrian and Swiss accents?
Standard German as spoken in Austria and Switzerland is generally recognized well. Strong regional dialects such as Alemannic Swiss German or Bavarian may be transcribed less reliably, since automated models are trained primarily on Standard German.
Does Sonix transcribe German with correct umlauts and ß?
Yes. Transcripts are produced in standard German orthography, including ä, ö, ü, and ß, and you can edit the text in the browser before exporting to Word, subtitles, and other formats.
Can Sonix transcribe German audio mixed with English?
Sonix transcribes one selected language per file, so choose German for German-language recordings. Occasional English loanwords common in German business speech appear in the transcript, but you should review those passages in the editor.
