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.

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