Production-ready Catalan to Welsh translation API

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

Catalan (Indo-European > Romance > Western Romance) and Welsh (Indo-European > Celtic > Brittonic) 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.

Catalan and Welsh through a single stream

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