Production-ready Slovak to Spanish translation API

Real Slovak 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.

Slovak (Indo-European > Slavic > West Slavic) and Spanish (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.

Real-time Slovak to Spanish translation

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