Understanding Korean VOB files
Standard South Korean, based on Seoul speech, dominates broadcast media and is what most speech recognition models are trained on. Regional dialects such as Gyeongsang, Jeolla, and Chungcheong differ in intonation and vocabulary, and Jeju speech is divergent enough that linguists often classify it as a separate language.

Frequently asked questions
How to improve the accuracy of your Korean transcripts?
Start by improving the quality of the Korean VOB 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 Korean VOB file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Korean VOB file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from VOB, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Korean with Sonix:
Why is my DVD split into several VOB files?
The DVD-Video specification limits each VOB segment to 1 GB, so longer titles are stored as sequential files (VTS_01_1.VOB, VTS_01_2.VOB, and so on) inside the VIDEO_TS folder. You can transcribe each segment separately or join them into a single file first for one continuous transcript.
My VOB has multiple audio tracks — which one gets transcribed?
VOB files can multiplex several audio streams, such as different languages or a commentary track. Transcription uses one audio stream at a time, so if you need a track other than the default, extract or remux that stream before uploading.
Can Sonix transcribe Korean audio and video files?
Yes. Upload your Korean recording and Sonix generates a transcript in Hangul that you can edit in the browser alongside the synced audio, then export to formats like DOCX, PDF, and SRT.
Does Korean transcription handle regional dialects like Gyeongsang or Jeolla?
Automated models are trained primarily on Seoul-standard Korean, so they generally handle regional accents but strong dialect speech may need more editing. You can review and correct those passages in the synced transcript editor.
Can I translate a Korean transcript into English?
Yes. After transcribing, you can translate the Korean transcript into English and other languages within Sonix, then export the translated documents or subtitles.
