Catalan to Spanish speech translation API

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

Trusted by

Production-ready Catalan to Spanish translation API

Real Catalan 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.

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

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