Italian to Portuguese speech translation API

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

Trusted by teams building global voice products

Production-ready Italian to Portuguese translation API

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

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