Production-ready English to Dutch translation API
Real English 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.
English 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.
Real-time English to Dutch translation
Soniox streams the English transcript and the Dutch translation on the same connection, word by word, so meaning lands while the speaker is still talking.
One-way translation
Translate live English into Dutch. Everyone in the conversation sees the same translated stream.
Two-way English and Dutch conversation
