Production-ready Portuguese to Latvian translation API

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

Portuguese (Indo-European > Romance > Western Romance) and Latvian (Indo-European > Baltic) 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.

Real-time Portuguese to Latvian translation

Soniox streams the Portuguese transcript and the Latvian translation on the same connection, word by word, so meaning lands while the speaker is still talking.
