Understanding Korean AMR 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 AMR 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 AMR file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Korean AMR file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AMR, 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 AMR file play on my computer?
AMR is a mobile telephony codec that many desktop media players do not support out of the box. Players such as VLC can open it, or you can convert the file to MP3 or WAV for wider compatibility.
Is AMR audio good enough for transcription?
Usually yes for clear voice recordings, since the codec is designed around the human speech range. Recordings made at the lowest bit rates or with heavy background noise carry less audio detail, which can reduce transcript clarity.
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.
Trusted by professionals worldwide
Fast, easy transcription. Also the ability to edit in the software with the recording before exporting is a great feature. I have already recommended you to a friend.
The UI is da bomb with so many great features including the one where I can highlight a passage and download as a clip. So very useful! It’s editing and transcription combined!!
