Live Multilingual Captions for International Conferences

Speakers talk in their own language, and everyone in the room reads their own language on their phone. No interpreter, no headsets, no app to install; scan one QR code and you are in.

How it works

1The organizer opens a session

We set up the session for you and give you three links with QR codes: speaker, audience and screen. The session closes by itself after the event date.

2Speakers talk into a phone or laptop

A speaker scans the “speaker” QR, enters a name, taps the microphone and starts. Several speakers or panelists can use their own phones at the same time; captions show who is talking.

3Audio is transcribed and translated on campus

The audio goes to NCKU's GPU server, which transcribes it and translates it into every language the audience has chosen. Captions usually appear 2 to 6 seconds after a sentence ends.

4Everyone reads their own language

Attendees scan the “audience” QR and pick a language; the interface switches to that language too, and the phone can read the captions aloud. The venue screen opens the “screen” link, which scrolls like a chat and can split into two columns on wide screens.

Supported languages

Speakers can talk in: Chinese (中文)EnglishJapanese (日本語)Korean (한국어)Thai (ไทย)FilipinoVietnamese (Tiếng Việt)Hindi (हिन्दी)Taiwanese

Captions can be shown in: Chinese (中文)EnglishJapanese (日本語)Korean (한국어)Thai (ไทย)FilipinoVietnamese (Tiếng Việt)Hindi (हिन्दी)

One session can run several caption languages at once; each attendee picks their own. The audience interface itself exists in these languages.

Features

Where it has been used

EventSetting
2026 International Conference on Interdisciplinary Arts (NCKU College of Liberal Arts, 21–22 Oct 2026)Two full days of Chinese, English and Japanese captions; many speakers taking turns on their phones; large captions projected in the hall.
2026 Naresuan University visit (NCKU College of Science and Science Education Center, 27–28 Oct 2026)Chinese, English and Thai captions throughout talks, discussions and site visits, with several phones taking turns.

What you need

Recommended browsers

The speaker and audience pages keep the screen awake by themselves (Screen Wake Lock: Safari 16.4, Chrome 85, Edge 90, Firefox 126 or later), so no need to change the phone's auto-lock. In our tests iPhone Safari and Android Chrome keep capturing after switching to another app, but that depends on the OS version and power-saving settings, so keep the speaker page in front; an incoming call always interrupts it.

DeviceRecommendedNotes
iPhone / iPadSafariEvery browser on iOS uses the same engine; Safari is the most stable, and the page keeps the screen on. A phone call interrupts capture, so turn on Do Not Disturb on the speaker's phone.
AndroidChromeThe page keeps the screen on. Set Chrome's battery usage to “Unrestricted” (Settings → Apps → Chrome → Battery) so power saving does not pause it while capturing in the background.
Windows laptopChrome or EdgeCapture continues with the window in the background and the page prevents sleep. Do not close the lid or let the laptop sleep.
Mac laptopChromeSame as above. Safari 16.4 or later also works, but keep the Safari window in front.

A link opened inside LINE lands in LINE's built-in browser, where the microphone is unavailable; our links jump to the phone's browser automatically. If that does not happen, copy the address into Safari or Chrome.

Limitations, stated up front

This is a service built and still being improved on campus, not a commercial product.
