Guests don't need a Zoom seat
Attendees who only want the translation can open the link alone.
Use case
If you run a handful of bilingual webinars a year, an enterprise interpretation contract is the wrong shape. tlive charges for event time, and adds one step to the Zoom workflow you already run.

Registration, reminders and recording are untouched.
Choose "meeting audio" or "both" so remote speakers are translated too.
Or put the QR code on your opening slide. Either works.

Level
Attendees who only want the translation can open the link alone.
With "both" selected, the speaker and the person asking are both translated.
Source text, translation and a summary for your event record or content reuse.
Ten minutes before you go live, run a sound check on the same link. If the level meter moves, your guests will hear it — that is the whole test.
Sign up and a test event is ready immediately. Use your own voice and your own material to judge the translation quality. Thirty minutes is enough for a full rehearsal.
