From K-content creators to Korean-American communities and cross-Pacific business, Korean transcription demand keeps growing — and Hangul's phonetic elegance suits speech recognition well. Trustample outputs natural Korean text with proper spacing and punctuation.
Students of Korean use transcripts as study aids (listen, read, replay any sentence with one click); businesses pair the transcript with Pro's English translation for meeting notes both offices can read.
Set the spoken language to Korean before uploading — it routes the audio to the right model and beats auto-detect on casual speech. An hour of free transcription each month (files to 30 minutes, TXT export, card-free) gets you started; sermon-length and lecture-length recordings are where the paid tiers take over, with files up to 3 hours on Basic and 6 hr 40 min on Pro.
How it works
- 1Set 'Spoken language' to Korean under the upload box.
- 2Upload the recording or video.
- 3Edit inline, export, and translate to English on Pro.
Frequently Asked Questions (FAQs)
Does it handle honorifics and casual banmal?
Both — the transcript reflects what was said, formal or casual. Very fast variety-show-style overlapping speech is the hardest case.
Is Hangul spacing handled correctly?
Yes — output follows standard Korean spacing conventions, and anything odd is a one-click inline fix.
Can I transcribe Korean church sermons or lectures?
Yes — long-form single-speaker Korean is close to a best case. Basic covers files up to 3 hours; Pro up to 6 hr 40 min.
How do Korean transcripts export?
TXT, DOCX, SRT and VTT all carry Hangul perfectly. For PDFs, export DOCX and print from Word — the built-in PDF font is Latin-only.
Can I translate a Korean recording to English?
On Pro, yes — Korean transcript first, stored English translation second, both kept together so a mishear shows up as a checkable Hangul error rather than vanishing into the English. Free route: export the Korean text and use any free translator.
How does it handle Konglish and English loanwords?
Konglish loanwords written in Hangul come out as Korean writes them (컴퓨터, 미팅), and short English phrases inside Korean speech usually survive as English. Sustained sentence-switching between the languages is harder — pick the dominant one.
An honest note: Fast overlapping speech — variety-show banter, heated multi-person debate — is the hard case for Korean, as for every language. Single-speaker and turn-taking audio does well; expect a heavier editing pass when everyone talks at once.
