Production-ready Catalan to Portuguese translation API
Real Catalan 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.
Catalan and Portuguese both belong to the Indo-European > Romance > Western Romance family, so cognates and shared structure carry over cleanly into the translated Portuguese output.
Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.

}Catalan and Portuguese through a single stream
Catalan 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: "ca" and target_language: "pt". It runs on the same WebSocket and the same model, with no extra round trip.
