German to Portuguese speech translation API

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

Trusted by

Production-ready German to Portuguese translation API

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

German (Indo-European > Germanic > West Germanic) and Portuguese (Indo-European > Romance > Western Romance) 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.

German and Portuguese through a single stream

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

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