Slovak to Spanish speech translation API

Stream Slovak (Slovenčina) speech and get Spanish (Español) back in real time. One WebSocket, ISO codes sk to es, and ultra-low latency for voice agents and live apps.

Trusted by

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.

Slovak and Spanish through a single stream

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

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