Trusted by teams building global voice products
Production-ready Welsh to Catalan translation API
Real Welsh 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.
Welsh (Indo-European > Celtic > Brittonic) and Catalan (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 Welsh to Catalan translation

High quality Catalan output
Same model across every language, including historically underserved ones.
Native-speaker Welsh STT accuracy
Accurate Catalan translation starts with accurate Welsh recognition across accents and language switching.
Names, numbers, and domain terms
Preserved across the pair, including phone numbers, emails, and IDs.

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