What happened
SyncWords, a provider of live and on-demand video captioning, subtitling and voice translation, integrates the DeepL API into its live streaming workflows to deliver real-time translated captions in many languages. It runs the API in a Kubernetes-based environment and uses glossaries to keep terminology consistent.
Summary written by usedby from the source page, in English. The figures are those of DeepL and SyncWords, not ours.
- 4-8“Traditional live captioning and subtitling systems lagged behind by 4-8 seconds, making real-time engagement frustrating and disconnected.”
SyncWords had tested multiple AI translation tools to evaluate their ability to handle linguistic nuances, industry-specific jargon, and contextual subtleties, before integrating DeepL into its workflow.
Our customers needed higher-quality translations–especially in European languages–and we had to deliver. That’s why we brought DeepL into our live video workflows. Our clients actually asked us for them.
