German to Dutch speech translation API

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

Trusted by

Production-ready German to Dutch translation API

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

German and Dutch both belong to the Indo-European > Germanic > West Germanic family, so cognates and shared structure carry over cleanly into the translated Dutch output.

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