Understanding Korean FLV 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 FLV 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 FLV file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Korean FLV file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from FLV, 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 FLV file play on my computer?
FLV was designed for Adobe Flash Player, which was discontinued at the end of 2020, so modern browsers and many media players no longer support it. Players such as VLC can still open FLV files, or you can convert them to MP4 for broader compatibility.
Do I need to convert FLV to MP4 before transcribing?
No, FLV files can be uploaded directly for transcription. Converting to MP4 is only needed if you also want the video to play in modern browsers or editing software.
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.

Sonix is the best transcription program I've ever used. It was almost error-free. I wish I could have used it longer!
Amazing for foreign videos that need subtitles. The platform is super easy to use and gave me EXACTLY what I was looking for.
