Korean to Croatian speech translation API

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

Trusted by

Production-ready Korean to Croatian translation API

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

Korean (Koreanic) and Croatian (Indo-European > Slavic > South Slavic) 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 Croatian in Latin, so Soniox emits correctly scripted Croatian text.

Korean and Croatian through a single stream

Korean to Croatian translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Croatian 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: "hr". It runs on the same WebSocket and the same model, with no extra round trip.
