How it works in Seoul
Our engineer on site
Our engineer sets up near the audio desk with our own laptop, audio interface and cables, takes one line output from the console and sound checks with the venue's AV team. For multi-hall shows at COEX or KINTEX, each room or stage gets its own setup and QR code.
Guests scan and choose
Guests scan a QR code and choose Korean, English, Japanese or another language you offer. Captions open in the phone browser with no app, for up to 500 audience phones.
Phones, screens and stream
Captions and AI voices reach phones, surtitles on LED walls and a transparent overlay for your livestream about two seconds after each sentence. Korean brand names and product terms are loaded in advance so they come out right.
Planning live translation for an event in Seoul
- Send the agenda, speaker names, company and product terms a week before, so they appear correctly in every language.
- Ask the venue’s AV team for one line output from the mixer and a table with power next to the audio desk for our engineer.
- Book a wired internet line for that table in large halls, where shared Wi-Fi gets busy.
- Put the QR code on the stage screens, signage and seat cards, and mention it in the opening remarks.
- Plan a short sound check with our engineer before doors open on each day.
