Trusted by

Production-ready English to Italian translation API

Real English 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.

English (Indo-European > Germanic > West Germanic) 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.
