Live AI captioning
Go beyond LinkedIn’s English-only closed captions. Embed EIA-608 captions in the seven languages the standard supports, including English, Spanish, French, Portuguese and Italian, into your LinkedIn Live. Or offer real-time captions on a standalone page.
Bring your own captioner
Prefer a professional captioner for marquee streams? Bring your own: caption ingest from standard steno software runs over a direct EIA-608 Control-A connection.
Live AI subtitling
Expand reach and brand exposure with real-time AI subtitles, set up in seconds without altering your LinkedIn Live workflow. Full API support to automate translation.
StreamYard, Restream and more
Works with StreamYard, Restream, OBS Studio, and other RTMP(S) tools people use to go live on LinkedIn.
Custom ASR dictionaries
Add specialized terminology, acronyms, and proper names to raise accuracy for your events. Keep as many dictionaries as you need.
Concurrent streams
Fully cloud-based, so you can run many concurrent LinkedIn Live events.
AI dubbing
Live AI dubbing for LinkedIn Live
Captions reach the audience that reads. Dubbing reaches the audience that listens. Vocalics, the SyncWords AI dubbing offering, dubs live news, sports and narrated programming in real time.
Dub into 86 languages
Natural-sounding AI dubbing in real time across 86 languages, with 900+ voices and regional accent options.
The speaker stays themselves
Voice transfer carries the original speaker's tone, pacing and emotion in real time across 38 languages. Preset voices and voice casting cover the rest.
One stream per language
LinkedIn Live carries one audio track per stream, so each dubbed language comes back as its own ready-to-publish stream: a Spanish broadcast running alongside your English one. Closed captions and subtitles are included with every dub.
Beyond embedded captions
Fits your LinkedIn workflow, and the rest of your stack
The same live pipeline adds captions, subtitles and AI audio translation across your other streaming protocols too.
HLS
Insert real-time captions, subtitles and AI audio tracks straight into an HLS livestream, on any device or screen.
SRT
Add real-time captions to Secure Reliable Transport streams from virtual studios and remote productions.

Automate every stream
Create, schedule, update and monitor caption events programmatically, and automate captions for every RTMP(S) stream.
Non-destructive delivery
Caption and subtitle tracks are added alongside your video, leaving your original stream untouched.
Helps meet accessibility goals
Captions make LinkedIn Live events easier to follow and help you meet your accessibility obligations.
