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.
