Live caption translations let you deliver real-time, AI-translated captions in 99 languages during your live events, so viewers can follow along in their own language as your event streams.
This feature is available to Custom and Enterprise customers.
Translated captions are generated from your event's automatic closed captions, so automatic closed captioning must be enabled for your event. Learn more in About automatic closed captioning for live events.
How it works
- Organizers pre-select the target languages in the event's caption settings before going live.
- During the broadcast, viewers choose their language from the CC menu in the player — switching is instant, with no reload.
- You can offer translated captions in up to 10 languages at the same time per event.
Set up translated captions
Target languages are configured in your live event settings before you go live:
- Open your live event's settings.
- Go to the Captions section.
- Make sure automatic closed captioning is enabled — translated captions are generated from it.
- Add the target languages you want to offer (up to 10).
Language settings lock once your stream starts. Add or change target languages before going live — they can't be edited once the event is live.
How viewers choose their language
During the broadcast, viewers select the [CC] button in the player and choose their preferred language. The selected language switches instantly, with no need to reload the player.
Translated captions on the recording
When your event ends, the translated captions are automatically regenerated on the VOD recording, so the languages you offered live remain available on the archived video.
Frequently asked questions
How many languages can I translate at once?
You can offer translated captions in up to 10 languages simultaneously per event.
Can I add languages once the event is live?
No. All language settings lock when the stream starts, so configure them before going live.
What happens to the translations after the event?
Translated captions are automatically regenerated on the VOD recording once the event ends.
Is this the same as multiple audio tracks?
No. They're separate, complementary features. Multiple audio tracks provide separate interpreter audio streams, while live caption translations are AI-generated translated text captions created from your event's primary audio.
Can I use live caption translations with low-latency streaming?
No. Translated captions are generated from your event’s automatic closed captions, and automatic closed captions aren’t available when low-latency streaming is enabled — the two settings can’t be used on the same event. Keep your event on standard latency to offer translated captions. Learn more in How to enable low-latency streaming.
