Spanish to Italian speech translation API

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

Trusted by

Production-ready Spanish to Italian translation API

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

Spanish (Indo-European > Romance > Western Romance) and Italian (Indo-European > Romance > Italo-Dalmatian) 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.
