Portuguese to Russian speech translation API

Stream Portuguese (Português) speech and get Russian (Русский) back in real time. One WebSocket, ISO codes pt to ru, and ultra-low latency for voice agents and live apps.

Trusted by

Production-ready Portuguese to Russian translation API

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

Portuguese (Indo-European > Romance > Western Romance) and Russian (Indo-European > Slavic > East Slavic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Portuguese is written in Latin and Russian in Cyrillic, so Soniox emits correctly scripted Russian text.

Portuguese and Russian through a single stream

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

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