Polish to Portuguese speech translation API

Trusted by teams building global voice products
Production-ready Polish to Portuguese translation API
Real Polish speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Portuguese while the speaker is still talking.
Polish (Indo-European > Slavic > West Slavic) and Portuguese (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.
Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.
A breakthrough in real-time Polish to Portuguese translation

High quality Portuguese output
Same model across every language, including historically underserved ones.
Native-speaker Polish STT accuracy

Preserved across the pair, including phone numbers, emails, and IDs.

}Polish and Portuguese through a single stream
Polish to Portuguese translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Portuguese translation streams mid-sentence in the same labeled token stream.
Turn it on by adding a translation block with source_language: "pl" and target_language: "pt". It runs on the same WebSocket and the same model, with no extra round trip.
