Everything you need to caption and localize your Vimeo livestream
Send your RTMP(S) stream to SyncWords, get it captioned or translated in real time, then push it onto Vimeo. Nothing changes in how you produce the stream.

Live AI captioning
Automatic captions generated in real time, with translated subtitles alongside. Embedded EIA-608 covers the seven languages the standard supports, including English, Spanish, French, Portuguese and Italian.
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.
Translated on the fly
Add real-time AI subtitles in seconds without changing your workflow, so a Vimeo live event can reach viewers beyond its home language.
Any RTMP(S) encoder
OBS Studio, Wirecast, vMix, Streamlabs, XSplit, Teradek, Restream, StreamYard and more. If it speaks RTMP(S), it works.
Custom ASR dictionaries
Load specialized terminology, acronyms and proper names to lift accuracy on your programming. Keep as many dictionaries as you need.
Concurrent streams
Fully cloud-based, so you can run many concurrent livestreams at once.
AI dubbing
Live AI dubbing for Vimeo
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
Vimeo carries one audio track per livestream, so each dubbed language comes back as its own ready-to-publish stream. Closed captions and subtitles are included with every dub.
Beyond embedded captions
Fits your Vimeo workflow, and the rest of your stack
Vimeo is one destination. The same live pipeline adds captions, subtitles and AI audio translation across your other 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.
AWS Elemental
Already on AWS Elemental? SyncWords slots into MediaLive and MediaPackage to keep your livestreams accessible around the clock.
Automate every stream
Create, schedule, update and monitor caption events programmatically. Automate captions for every RTMP(S) stream from your own stack.
Non-destructive delivery
Caption and subtitle tracks are added alongside your video, so your original stream is untouched.
Helps meet accessibility goals
Captions make live content easier to follow and help you meet your accessibility obligations for Vimeo events.
