Polish to Serbian speech translation API

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

Trusted by

Production-ready Polish to Serbian translation API

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

Polish (Indo-European > Slavic > West Slavic) and Serbian (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.

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

Polish and Serbian through a single stream

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