Persian to Spanish speech translation API

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

Trusted by

Production-ready Persian to Spanish translation API

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

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

Persian and Spanish through a single stream

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