Live AI captions
Automatic captions in real time, delivered as embedded EIA-608 for players that expect broadcast captions.
Translated subtitles
Translated subtitles in real time, added without changing your channel so a single feed reaches viewers well beyond its home language.
Slots into MediaLive & MediaPackage
SyncWords sits inside your existing AWS Elemental workflow. No re-architecting the channel, and no on-site caption encoder.
AI dubbed audio
Add AI voice dubbing with Vocalics for news, sports and narrated programming. It keeps the speaker's tone, pacing and emotion. Closed captions and subtitles are included with every dub.
Higher accuracy on your terms
Load custom ASR dictionaries with names, acronyms and product terms. Per-language glossaries keep translated wording consistent.
Built for 24/7 linear
Fully cloud-native, so you can run many concurrent channels at once and keep round-the-clock linear streams captioned without downtime.
AI dubbing
Live AI dubbing for AWS Elemental
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.
Audio tracks in your transport stream
In SRT and MPEG-TS workflows, dubbed audio rides as additional audio tracks alongside the original, with codec and PID control per track, so downstream systems expose a language menu to the viewer. Closed captions and subtitles are included with every dub.
How your audience sees it
Reach every viewer, in their language
Captions and subtitles reach viewers however they watch, from a player-native track in your AWS output to a shareable link.
MediaPackage tracks
WebVTT and IMSC caption tracks in your MediaPackage output, displayed player-native on any desktop or mobile device.
Embedded EIA-608
Broadcast-standard captions carried in the stream for players and downstream systems that expect them.
SRT & HLS ingest
Send SyncWords your feed over SRT or HLS and get it back captioned in real time, ready for the rest of the pipeline.
