Production-ready English to Serbian translation API

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

English (Indo-European > Germanic > West Germanic) and Serbian (Indo-European > Slavic > South Slavic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

English is written in Latin and Serbian in Cyrillic, so Soniox emits correctly scripted Serbian text.

Real-time English to Serbian translation

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