What are SyncWords live translations and subtitles?

SyncWords live translations and subtitles convert spoken audio into readable text in multiple languages in real time. Subtitles can be delivered during live broadcasts, live events, and live streams from a single live workflow, reaching both in-room audiences and remote viewers.

How accurate are live translations?

Live translations are highly accurate for common language pairings and simple content. Translations are optimized for clarity and speed in real-time environments. Accuracy is balanced with latency to support fast-moving dialogue, unscripted moments, and live production timing.

How much delay do live translations introduce?

SyncWords delivers translations with low and predictable latency suitable for live events and broadcasts, helping subtitles remain readable and aligned with the original audio.

Do translations work for large or complex live productions?

Yes. SyncWords is designed for high-scale live environments, including multi-language conferences, hybrid events, and broadcast productions where timing, stability, and coordination are critical.

What languages are supported?

SyncWords supports a wide range (over 160) languages for live translation and subtitles. Multiple languages can be delivered at the same time from a single live source.

Are translated subtitles accessible and compliant?

Yes. Translated subtitles support accessibility and inclusion requirements for both live events and broadcast content, helping organizations reach global audiences more effectively.

What formats and workflows are supported?

SyncWords supports industry-standard formats and live delivery workflows used across events, streaming, and broadcast environments, including SRT, HLS and player-based subtitle delivery.

How long does setup take?

Setup is fast and scalable. Translation and subtitle workflows can be configured quickly for broadcast, live streams, single sessions or expanded across multi-room, multi-language productions.

When should teams use live translation and subtitles?

When content needs to be understood across languages in real time - on-site, online, and on-air - without adding complexity to a live production.
