Polish to German speech translation API

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

Trusted by

Production-ready Polish to German translation API

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

Polish (Indo-European > Slavic > West Slavic) and German (Indo-European > Germanic > West 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.

Polish and German through a single stream

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

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