Korean to German speech translation API

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

Trusted by

Production-ready Korean to German translation API

Real Korean 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.

Korean (Koreanic) 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.

Korean is written in Hangul and German in Latin, so Soniox emits correctly scripted German text.

Korean and German through a single stream

Korean 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: "ko" and target_language: "de". It runs on the same WebSocket and the same model, with no extra round trip.
