Production-ready Spanish to Basque translation API

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

Spanish (Indo-European > Romance > Western Romance) and Basque (Language isolate) 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 Spanish to Basque translation

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