What is SyncWords?

SyncWords turns a single live video feed into real-time captions, translated subtitles and AI dubs for broadcast, streaming and live events. Captions are delivered from the cloud with no hardware encoder required, and reach every platform your stream goes — SRT, HLS, RTMP and social destinations. Usage is billed by the hour, per language and per output.

How to use SyncWords?

Connect your live feed over SRT, MPEG-TS, CMAF ingest, HLS or RTMP. SyncWords generates captions, subtitles and dubs in the cloud. Deliver to your platforms and players through the widget, QR code, embeddable player or the Live API.

SyncWords Core Features

Live captioning

Real-time captions delivered from the cloud with no hardware encoder and no contracted human captioner. Custom ASR dictionaries recognize names, acronyms and specialist terminology.

Translated subtitles

Translated subtitles in many languages, kept consistent across outputs with translation glossaries for names and preferred wording. Outputs WebVTT, DVB, Teletext and TTML.

AI dubbing

Natural-sounding AI dubs that keep the original speaker's tone, emotion and rhythm. Three tiers: preset voice, voice casting and voice transfer.

Live API and delivery

SyncWords Frequently Asked Questions

Do we need a hardware caption encoder?

No. Captions are delivered from the cloud, with no encoder and no contracted human captioner. If you already own caption encoders, SyncWords can drive them over IP, so you migrate to the cloud path at your own pace.

How much latency does captioning add?

Captions can land with no perceptible delay when the buffer absorbs processing time, and the video path itself adds about a half-second latency in SRT workflows. The full path-by-path picture is documented on the latency page.

Is it reliable enough for 24/7 broadcast?

Dual-pipeline A/B failover with SCTE-35 pass-through, 99.99% uptime with an SLA carrying a financial remedy on Broadcast and Enterprise plans, a 24/7 engineering team, and primary plus backup resources in any AWS region.

Is the dubbing voice cloning?

No. In dubbing the words are the speaker's own words in another language. SyncWords offers three dubbing tiers — preset voice, voice casting, and voice transfer — which keeps the original speaker's tone, emotion and rhythm intact in real time.

How is SyncWords priced?

Usage-based, billed in hours and charged per language and per output. A one-hour session delivering Spanish and French subtitles plus a Spanish dub counts as three hours. The effective rate falls as committed volume rises, with no hardware cost and no per-channel licence.
