Understanding Croatian RM files
Croatian has three major dialect groups: Shtokavian, the basis of the standard language; Kajkavian, spoken around Zagreb and northern Croatia; and Chakavian, heard along the Adriatic coast and islands. Spoken Croatian is also very close to Serbian, Bosnian, and Montenegrin, so identifying the correct language variant matters before transcription.

Frequently asked questions
How to improve the accuracy of your Croatian transcripts?
Start by improving the quality of the Croatian RM 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 Croatian RM file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Croatian RM file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from RM, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Croatian with Sonix:
Why won't my RM file play on my computer?
RM is a proprietary RealNetworks format that modern operating systems no longer support out of the box. You typically need RealPlayer, or a player like VLC that offers partial RM support.
Should I convert my RM files to a modern format?
For long-term preservation, converting to a widely supported format like MP4 is a reasonable step, since RM playback support continues to shrink. Keep the original file as well, because re-encoding a lossy format can reduce quality slightly.
Can Sonix transcribe Croatian audio and video files?
Yes. Upload your Croatian audio or video file, select Croatian as the language, and Sonix generates a transcript you can edit and export.
Does Croatian transcription handle dialects like Kajkavian and Chakavian?
The model is trained on standard Croatian, which is based on Shtokavian. Strong Kajkavian or Chakavian dialect speech may need more correction in the built-in editor.
What is the difference between Croatian and Serbian transcription?
The two languages are closely related and mutually intelligible in speech, but they use different standard vocabularies and scripts — Croatian uses the Latin alphabet, while Serbian uses both Cyrillic and Latin. Choose the language that matches your audio so the transcript follows the right conventions.
