Persian to Finnish speech translation API

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

Trusted by

Production-ready Persian to Finnish translation API

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

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

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

Persian and Finnish through a single stream

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

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