Production-ready Bulgarian to German translation API

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

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

Bulgarian is written in Cyrillic and German in Latin, so Soniox emits correctly scripted German text.

Real-time Bulgarian to German translation

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

Does Soniox handle Bulgarian dialects and accents?

Yes. Soniox handles Bulgarian dialects like Eastern Bulgarian and Western Bulgarian in a single model, so German translation stays accurate across regions.
