Real-time Bulgarian translation across 60+ languages

Bulgarian is spoken by over 8 million people worldwide primarily in Bulgaria, with speakers around the world. Real Bulgarian conversations carry accents, regional dialects, code switching, and domain-specific vocabulary. Most translation systems break on exactly that variation, or wait for a sentence to finish before producing anything usable.

Soniox handles that variation in a single model and translates Bulgarian as it is spoken, not after the fact. Names, numbers, addresses, IDs, and domain terms carry through into the translated transcript, and Bulgarian works as both a source and a target language — across its own Indo-European > Slavic > South Slavic family and any of 3,600 language pairs in total.

Real-time Bulgarian translation

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

Turn on Bulgarian translation with a config change

Translation is part of the Soniox Speech-to-Text API, not a second service. Add a translation block to your request and translated tokens come back interleaved with transcripts on the same stream.

  "model": "stt-rt-v5",
  "translation": {
    "type": "one_way",
    "target_language": "bg"
  }

Frequently asked questions

Does Soniox translate Bulgarian in real time?
Yes. Soniox streams Bulgarian translation while speech is still happening, so users see or hear meaning immediately instead of waiting for the sentence to end.
What language pairs are supported for Bulgarian?
Soniox supports translation between Bulgarian and any of 60+ supported languages — 3,600 language pairs in total. Both Bulgarian as the source and Bulgarian as the target are supported.
How does two-way Bulgarian translation work?
Two-way translation lets both sides of a conversation speak in their own language and hear the other side in theirs. A Bulgarian speaker can talk in Bulgarian while the other party hears their own language in real time, and vice versa.
Does Soniox handle dialects and accents in Bulgarian?
Yes. Soniox handles Bulgarian dialects like Eastern Bulgarian and Western Bulgarian in a single model, along with accents and language switching, so live translation stays accurate across regions and registers.
Can Soniox translate names, numbers, and domain terms in Bulgarian?
Yes. Soniox preserves the details that matter — names, phone numbers, emails, IDs, addresses, verification codes, and domain-specific terminology — in both the Bulgarian transcript and the translated output.
Which other providers support live Bulgarian translation?
Based on their public docs, OpenAI, Azure, and Speechmatics list Bulgarian as a supported source language for real-time translation. Soniox is the only one of them that also supports two-way live translation across 60+ languages.
How fast is Bulgarian translation?
Soniox streams translated text as Bulgarian is being spoken, with ultra-low latency. Translation arrives before the sentence ends, rather than after long caption delays.
What can I build with Bulgarian translation?
Common use cases include multilingual voice agents, live interpreters, multilingual meetings, customer support and contact centers, real-time translated captions and subtitles, and accessibility and communication tools — all with Bulgarian as a source or target.
