Understanding Korean M4V 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 M4V 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 M4V file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Korean M4V file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from M4V, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Korean with Sonix:
Why won't my M4V file play on my computer?
Movies and TV shows purchased or rented from the iTunes Store often carry FairPlay DRM, which restricts playback to authorized Apple apps and devices. DRM-free M4V files play in most modern media players, including VLC.
Can I just rename an M4V file to MP4?
Often yes, because both extensions use the same MPEG-4 container, so renaming a DRM-free file usually works. Playback can still fail if the file uses AC-3 audio and the target player does not support that codec.
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.
