Production-ready Bulgarian to Serbian translation API
Real Bulgarian 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.
Bulgarian and Serbian both belong to the Indo-European > Slavic > South Slavic family, so cognates and shared structure carry over cleanly into the translated Serbian output.
Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.
Real-time Bulgarian to Serbian translation
Soniox streams the Bulgarian transcript and the Serbian translation on the same connection, word by word, so meaning lands while the speaker is still talking.
One-way translation
Translate live Bulgarian into Serbian. Everyone in the conversation sees the same translated stream.
Two-way Bulgarian and Serbian conversation
Each side speaks naturally and hears the other in their own language. Use it for live interpreters, bilingual voice agents, travel assistants, and customer support.
Bulgarian and Serbian through a single stream
Set the source and target codes once. Transcript and translation arrive interleaved on one labeled token stream, with no extra round trip.
