Understanding Korean WAV 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 WAV 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 WAV file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Korean WAV file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from WAV, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Korean with Sonix:
Do I need to convert WAV to MP3 before transcribing?
No, WAV files can be uploaded and transcribed directly. Keeping the original WAV avoids the compression artifacts an MP3 conversion introduces, though the larger file may take longer to upload.
Why are my WAV files so large?
WAV stores uncompressed PCM audio, so CD-quality stereo uses roughly 10 MB per minute. Converting to a compressed format like FLAC or MP3 reduces the size if you need to save space after transcription.
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.
