Case study 
Partnership 
SyncWords partners with Signapse to deliver photorealistic ASL translation in real time
A photorealistic ASL signer generated from your live stream and composited into the program, in the same SRT workflow you already run.
See our partnersStart with the audience
Let more people follow. Reach them in their language.
Add same-language captions for accessibility and comprehension. Add translated subtitles or AI dubbing when the program needs to cross a language barrier.
Accessibility
Caption the stream without an encoder
Put captions directly into live broadcast streams from the cloud—without re-encoding video or installing caption hardware.
Half a second to the video. Under two to the captions.
Keep live captions close to the moment without making the audience wait for the program.
Pay for the captioning. Not the channel count.
Pricing follows usage, with no per-channel licence. Higher committed volume lowers the effective hourly rate.
Your names, before airtime
Load custom dictionaries with presenters, players, places, acronyms and specialist terms the general model cannot be expected to know.
Native to the AWS media stack
Work directly with MediaConnect, MediaLive, MediaPackage, CloudFront and S3.
Caption the room in under a minute
Start a session and get a branded URL and QR code in under 60 seconds. No video feed or attendee app required.
Human for the keynote. AI for the breakouts.
Choose professional CART or AI session by session without moving the event between vendors.
Put the words on every phone and wall
Let attendees read captions on their own devices while the same live page feeds house displays and confidence monitors.
Localization
Open a market during the next broadcast
Add translated subtitle and dubbed audio tracks to the feed already on air.
Keep the person inside the translation
Vocalics carries tone, pacing and emotion into another language in real time.
Send every attendee home understanding
One event link serves every language you enable.
Localize the library on autopilot
Drop files into an automated workflow and get captioned, subtitled and dubbed assets back.

Built for the awkward part
The clever AI is only half the job
The model writes the words. The harder part is getting captions, subtitles and dubbed audio through a live media chain without breaking what is already on air.
We wrote the muxer
Kobe Muxer is our hand-built MPEG-TS stack for EIA-608, Teletext, DVB-SUB, DVB-TTML and dubbed audio tracks.
Five places in the chain
Before the transcoder, between transcoder and packager, at the HLS origin, over RTMP or straight to the viewer.
Failure has somewhere to go
Dual A/B pipelines, independent SRT paths, regional backup and 24/7 engineering support are built for live production.
Bring us the feed everyone else found difficult
The noisy stadium. The language nobody volunteered to attempt. The event that goes live tomorrow. Those are the useful demos.
