Portuguese to Catalan speech translation API

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

Trusted by

Production-ready Portuguese to Catalan translation API

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

Portuguese and Catalan both belong to the Indo-European > Romance > Western Romance family, so cognates and shared structure carry over cleanly into the translated Catalan output.

Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.

Portuguese and Catalan through a single stream

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