Serbian to Croatian speech translation API

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

Trusted by

Production-ready Serbian to Croatian translation API

Real Serbian 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.

Serbian and Croatian both belong to the Indo-European > Slavic > South Slavic family, so cognates and shared structure carry over cleanly into the translated Croatian output.

Serbian is written in Cyrillic and Croatian in Latin, so Soniox emits correctly scripted Croatian text.

Serbian and Croatian through a single stream

Serbian 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: "sr" and target_language: "hr". It runs on the same WebSocket and the same model, with no extra round trip.
