Understanding Korean MTS 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 MTS 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 MTS file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Korean MTS file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MTS, 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 MTS file play on my computer?
MTS files use the AVCHD transport-stream structure, which some default media players do not support, and clips copied out of the camcorder's AVCHD folder can lose playback context. Opening the file in VLC or remuxing it to MP4 usually resolves the issue.
Do I need to convert MTS to MP4 before transcribing?
No. You can upload the MTS file directly, and its audio track is extracted and transcribed the same way as an MP4 upload.
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.
