Live events FAQ
Do attendees need an app?
No. They scan a QR code and read captions on a web page on their own device, or tap a CC button inside your event app.
Does it work for in-person events?
Yes. The same page-based delivery works in stadiums, conference rooms and outdoor venues; captions can also be projected to a venue screen via OBS.
How fast can we go live?
Same day. A flagship international stadium tournament went from signed contract to live in a single day.
How many attendees and languages?
At least 10,000 simultaneous attendees in production, with simultaneous languages on one channel.
Can I get human-grade accuracy?
Custom ASR dictionaries help live AI captioning recognize your event's speaker names, sponsor names and specialist terminology.
We used to rent a hardware encoder. Now what?
Nothing to rent. SyncWords delivers a cloud widget, with no encoder and no human captioner required.
Is there support during the event?
Yes. A 24/7 coordination team and a live technician during your broadcast; a SyncWords services partner runs roughly 75 live sessions every Sunday on our platform.
