AI Translated bybarotalk

An actual live event screen. The moment Korean hits the mic, subtitles flow within a second or two.

An honest comparison with traditional interpretation

The era of spending $5.4K on event interpretation is over.

Same event, same quality — at half of what four human interpreters cost, with 30 target languages instead of 4.

Traditional interpretation
Reference

Human interpreters + booths + headsets

5,400USD/ 300-attendee conference · 4 languages
  • USD 600–1,200 per session (per language)
  • Booth and headset rental on top
  • Voice only — no subtitles, no transcript
  • Hits a ceiling at 2–3 simultaneous languages
  • Hard to correct mid-utterance

Your slides become the subtitle dictionary.

Upload your deck once — the same translation holds through the whole event.

Step 1

Upload your slides

PDF, PPTX, TXT — all fine. Just drop them in.

Step 2 · Term extraction
HER2표적치료Ondo FinanceRWA토큰화

The speaker's terms get pulled into the glossary automatically.

Step 3 · Accurate subtitles

HER2-positive breast cancer responds well to targeted therapy.

Terms mapped in the glossary stay consistent across the whole event.

HER2 양성 유방암은 표적치료에 반응을 잘 보입니다.

HER2-positive breast cancer responds well to targeted therapy.

1차 치료 객관적 반응률은 78%로 보고됐어요.

The first-line objective response rate was reported at 78%.

The slide's '표적치료' was mapped to the standard term 'targeted therapy' using prior knowledge.

Online mode

Now your online events get the same live translation.

Just like your in-person events — translate the audio from Zoom, YouTube, Google Meet, or Teams in real time. Not Zoom- or webinar-only: any tab that plays sound works.

ZoomYouTubeGoogle MeetTeamsWebex
STEP 1

Set source to "Screen/tab audio"

In the operator console, choose "Screen / tab audio" (the sound coming from a screen or tab) instead of a microphone.

STEP 2

Share tab audio

Pick the tab you want to translate and check "Share tab audio" so the sound goes through too. That's it.

STEP 3

Same captions everywhere

Captions flow as usual to attendees' phones and the LED screen, and to OBS (streaming software) too.

Works best in Chrome and Edge.

Live reliability

Live events are full of surprises.

Speech blurs, connections wobble, pronunciations slip — on stage, something goes wrong every minute. barotalk keeps it all flowing with almost no human help.

Safeguard 01

Fills in context when speech breaks up

LIVEKorean → English

“이게… 음… 그러니까 RWA 가…”

“So, about RWA, real-world assets…”

Even when the speaker stalls — "so… uh… you know, RWA is" — barotalk reads the prior context and slide glossary to render a clean sentence.

Subtitles stay smooth even when on-stage mics feed speech recognition uneven input.

Safeguard 02

Live subtitle fixes · auto reconnect

Mic reconnecting…Auto-recovered
“Ondo Finance” 온도Fixed instantly

If a subtitle reads awkward, the operator fixes it with one click on their laptop — the next subtitle reflects the correction. If the internet drops for a moment, the last captions stay on the LED, and the line reconnects the moment the signal returns.

Network jitter · mic fade · mispronunciation — none of it ever shows on stage.

No industry off limits

Any industry — just feed it the prior knowledge.

From blockchain to medicine to diplomacy, barotalk fits any field — accuracy rises to match each event's own terms.
