Captions, subtitles and AI dubbing for live video
SyncWords Live turns any live source into same-language captions, translated subtitle tracks and Vocalics dubs, then puts each output where your audience already watches.
What the audience receives
Start with the audience experience you need
Same-language captions for broadcast, streaming and platform delivery, generated by AI or supplied by a human captioner.
Real-time subtitle tracks for every market you want to reach, delivered alongside the live program.
Spoken translation that carries the speaker's delivery into a new language while preserving the atmosphere beneath it.
From feed to audience
Turn the live program into every audience experience
SyncWords Live builds captions, translated subtitles and dubbed audio in real time, then sends each output through the route that fits your operation.
-
Bring the feed you already have
Connect over SRT, RTMP, HLS or CMAF. Use the program audio, an existing caption feed or your own human captioner as the starting point.
-
Build the language layer
Recognize the program audio, apply dictionaries and glossaries, and produce captions, translated subtitles and dubbed audio in parallel.
-
Send each output where it belongs
Return language tracks to broadcast and streaming infrastructure, publish to direct destinations, or serve viewers through a web experience.
- Captions Same language Live output
- Subtitles Translated text Live output
- Vocalics Dubbed audio Live output
Every active output can run from the same service and the same source at the same time.
Delivery flexibility
It fits where your chain has room
Keep the encoders, transcoders, packagers, origins, players and vendors that make sense. SyncWords Live adds language tracks at the point your operation can support.
See every delivery pathBefore the transcoder
Send an SRT contribution feed through SyncWords and take back captions, subtitle tracks and dubbed audio inside the MPEG-TS output.
Before the packager
Add live text and audio tracks through CMAF ingest while the packager continues to own the final presentation.
At the origin
Write WebVTT into the HLS stream you already publish without copying or re-encoding the original video segments.
Direct to the destination
Reach social platforms, meeting tools, existing caption encoders and direct viewer experiences from the same live service.
The platform around the pipeline
A lot happens between source and audience
SyncWords Live covers the language work, the live operations around it and the handoffs on both sides. Here is the short version.
Source flexibility
Push or pull live media over the protocols already present in your operation.
AI or human input
Start with live speech recognition, your existing captions or a professional captioner.
Languages in parallel
Run captions, subtitle tracks and Vocalics dubs together in one live service.
Names that stay correct
Attach ASR dictionaries, translation glossaries and pronunciation rules to each service.
Scheduling and templates
Map a recurring channel once, schedule across time zones and start automatically at airtime.
Live monitoring
Watch service health, bitrate, runtime activity and every active language output while the program is on.
API and webhooks
Let broadcast automation, a scheduler or your own platform control the service lifecycle.
Every session leaves a file
Export the source or any translated language as TXT, SRT, WebVTT or DFXP, for the exact time window you need.
One view of the operating surface
Map the service once. Run it again and again.
A service keeps the source, outputs, destinations, dictionaries, styling and access settings together. Start it manually, put it on a schedule or hand control to your automation.
- Recurring broadcasts keep their configuration between runs.
- Role-based access gives each team the view and controls it needs.
- Multiple live services can run and be monitored at the same time.
- Usage stays visible by event, client, language and output.

Questions teams ask before the first feed
What is SyncWords Live?
SyncWords Live is the cloud platform for producing and delivering captions, translated subtitles and Vocalics dubs from live media. It includes the real-time language pipeline plus scheduling, monitoring, account controls, automation and delivery.
Do we need new hardware?
No. A cloud-first workflow needs no new caption encoder or appliance. If you already own a caption encoder and want to keep it, SyncWords Live can drive it over IP while the rest of the workflow moves at your pace.
Can we keep our current captioner?
Yes. SyncWords Live can ingest live captions from steno software or an existing caption feed, then use that text to create downstream subtitle and dubbing outputs.
Can one service deliver captions, subtitles and dubs together?
Yes. A single live service can create several text and audio outputs from the same source and deliver them to multiple destinations at the same time.
Can SyncWords Live be automated?
Yes. The Live API and webhook events can connect service creation, scheduling, start, stop and monitoring to your existing automation or platform workflow.
How is SyncWords Live priced?
Pricing is usage-based: hours are charged per language and per output. There is no per-channel licence or hardware cost, and the effective hourly rate falls as committed volume rises.
