Production-ready Swedish to Welsh translation API

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

Swedish (Indo-European > Germanic > North Germanic) and Welsh (Indo-European > Celtic > Brittonic) 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.

Real-time Swedish to Welsh translation

Soniox streams the Swedish transcript and the Welsh translation on the same connection, word by word, so meaning lands while the speaker is still talking.

Frequently asked questions

How do I translate Swedish to Welsh with the API?
Add a translation block to your real-time request with source_language "sv" and target_language "cy". Soniox transcribes Swedish and streams the Welsh translation over the same WebSocket.
Is Swedish to Welsh translation real-time?
Yes. Soniox streams Welsh while Swedish is still being spoken, so meaning arrives mid-sentence instead of after the sentence ends.
What about translating Welsh to Swedish?
That direction is supported too. See the Welsh to Swedish page, or use two-way translation to run both directions in one session.
Does Soniox handle Swedish dialects and accents?
Yes. Soniox handles Swedish dialects like Central Swedish, Finland Swedish, and Gotlandic in a single model, so Welsh translation stays accurate across regions.
Which other providers support Swedish to Welsh?
Based on their public docs, OpenAI, Google, and Azure list both Swedish and Welsh for real-time translation. Soniox is the only one that also supports two-way live translation across 60+ languages.
How fast is Swedish to Welsh translation?
Soniox streams Welsh as Swedish is being spoken, with ultra-low latency. Translation arrives before the sentence ends.
