Czech to Persian speech translation API

Stream Czech (Čeština) speech and get Persian (فارسی) back in real time. One WebSocket, ISO codes cs to fa, and ultra-low latency for voice agents and live apps.

Trusted by

Production-ready Czech to Persian translation API

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

Czech (Indo-European > Slavic > West Slavic) and Persian (Indo-European > Iranian > Western Iranian) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Czech is written in Latin and Persian in Arabic, so Soniox emits correctly scripted Persian text. Right-to-left output is handled directly in the token stream.

Czech and Persian through a single stream

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

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