Persian to Swedish speech translation API

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

Trusted by

Production-ready Persian to Swedish translation API

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

Persian (Indo-European > Iranian > Western Iranian) and Swedish (Indo-European > Germanic > North Germanic) 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 Swedish in Latin, so Soniox emits correctly scripted Swedish text. Right-to-left output is handled directly in the token stream.

Persian and Swedish through a single stream

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