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
ReferenceHuman 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

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.
