Build with API

Swedish to Norwegian speech translation API

Stream Swedish (Svenska) speech and get Norwegian (Norsk) back in real time. One WebSocket, ISO codes sv to no, and ultra-low latency for voice agents and live apps.

Trusted by teams building global voice products

Production-ready Swedish to Norwegian translation API

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

Swedish and Norwegian both belong to the Indo-European > Germanic > North Germanic family, so cognates and shared structure carry over cleanly into the translated Norwegian output.

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

Swedish and Norwegian through a single stream

Swedish to Norwegian translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Norwegian translation streams mid-sentence in the same labeled token stream.

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

Frequently asked questions

How do I translate Swedish to Norwegian with the API?
Add a translation block to your real-time request with source_language "sv" and target_language "no". Soniox transcribes Swedish and streams the Norwegian translation over the same WebSocket.
Is Swedish to Norwegian translation real-time?
Yes. Soniox streams Norwegian while Swedish is still being spoken, so meaning arrives mid-sentence instead of after the sentence ends.
What about translating Norwegian to Swedish?
That direction is supported too. See the Norwegian to Swedish page, or use two-way translation to run both directions in one session.
Swedish and Norwegian are both Indo-European > Germanic > North Germanic — does that affect quality?
Shared family structure and cognates generally help. Soniox uses the same model for every pair, so quality stays consistent whether the languages are closely related or not.
Does Soniox handle Swedish dialects and accents?
Yes. Soniox handles Swedish dialects like Central Swedish, Finland Swedish, and Gotlandic in a single model, so Norwegian translation stays accurate across regions.
Which other providers support Swedish to Norwegian?
Based on their public docs, OpenAI, Azure, and Speechmatics list both Swedish and Norwegian for real-time translation. Soniox is the only one that also supports two-way live translation across 60+ languages.
How fast is Swedish to Norwegian translation?
Soniox streams Norwegian as Swedish is being spoken, with ultra-low latency. Translation arrives before the sentence ends.
