Production-ready Welsh to Lithuanian translation API

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

Welsh (Indo-European > Celtic > Brittonic) and Lithuanian (Indo-European > Baltic) 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.

Real-time Welsh to Lithuanian translation

Soniox streams the Welsh transcript and the Lithuanian translation on the same connection, word by word, so meaning lands while the speaker is still talking.
