Trusted by

Production-ready Spanish to Slovak translation API

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

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

Spanish and Slovak through a single stream

Spanish to Slovak translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Slovak translation streams mid-sentence in the same labeled token stream.

Turn it on by adding a translation block with source_language: "es" and target_language: "sk". It runs on the same WebSocket and the same model, with no extra round trip.
