English to Danish speech translation API

Stream English (English) speech and get Danish (Dansk) back in real time. One WebSocket, ISO codes en to da, and ultra-low latency for voice agents and live apps.

Trusted by

Production-ready English to Danish translation API

Real English speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Danish while the speaker is still talking.

English (Indo-European > Germanic > West Germanic) and Danish (Indo-European > Germanic > North Germanic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.
