Dutch to Danish speech translation API

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

Trusted by

Production-ready Dutch to Danish translation API

Real Dutch 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.

Dutch (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.

Dutch and Danish through a single stream

Turn it on by adding a translation block with source_language: "nl" and target_language: "da". It runs on the same WebSocket and the same model, with no extra round trip.
