How it works

How do you translate a Bulgarian recording into English?

To translate Bulgarian audio to English, drop the recording on this page; it expects Bulgarian speech and writes English. The speech is transcribed in Cyrillic in short pieces, then each line is translated with its time. Read the English and check the Bulgarian whenever you need to.

  1. 1

    Add the Bulgarian recording

    A voice message, a call, a lecture or an interview: MP3, M4A, WAV or OGG.

  2. 2

    Bulgarian, then English

    Transcribed in Bulgarian and translated into English. Up to 30 minutes per recording.

  3. 3

    Save the English

    Copy it, or download text or Word; the Bulgarian transcript is saved separately.

What do you get from a Bulgarian recording?

An English transcript in timed paragraphs, ready to copy or save as a Word document, plus the Bulgarian transcript in Cyrillic with the same times. Pair them up whenever someone asks what exactly was said in Bulgarian.

How do Bulgarian names come out in English?

Spelled from the Cyrillic by sound. Familiar names usually land correctly, but less common ones may not: in our test “Раоник” came back as Raonic, while “Пике младши” became “Pique Jr.” instead of Piquet Jr. Check names before you quote them.

Раоник
English translationRaonic
MeantRaonic
Бризбейн
English translationBrisbane
MeantBrisbane
Пике младши
English translationPique Jr.
MeantPiquet Jr.

Does the English keep the shape of the Bulgarian sentence?

Often, yes. “Високата концентрация на токсина във водите често убива рибите” came back as “The high concentration of toxin in the waters often kills the fish”: the meaning is right and the sentence keeps its Bulgarian order. For a report, you may want to smooth such lines.

How well does Bulgarian speech come through in English?

Well. In our test, Bulgarian speech was transcribed cleanly and the English made from it rated good. A word the transcript misheard is still translated as heard, so the recording remains the last word on anything you plan to quote.

Do you work with Bulgarian recordings often?

NoteOwl understands Bulgarian on your Mac: it transcribes Bulgarian recordings and calls with unlimited transcription, labels each speaker and keeps every conversation searchable. For a Bulgarian transcript only, use Bulgarian audio to text.

FAQ

Questions about translating Bulgarian audio into English

Is the Bulgarian to English audio translator free?

Yes. 3 recordings a day, up to 30 minutes each, with no account. The English, the Bulgarian transcript and every download are included.

Can I translate a Bulgarian voice message?

Yes. Save or export the message as an audio file and drop it on the page. WhatsApp usually saves OGG or OPUS; most phone recordings are M4A.

Do I also get the Bulgarian transcript?

Yes. Switch the result to Original for the Bulgarian in Cyrillic, with the same times, and save it as text or SRT.

What if the speakers mix in English?

This page transcribes the whole recording as Bulgarian. For a mixed recording, use the main audio translator with the spoken language left on Detect automatically.

Does the English show who is speaking?

No. You get the words and their times without names. NoteOwl on a Mac labels each speaker in its transcripts.

Is my recording uploaded?

No. Your browser reads it and sends short pieces of the sound to a cloud AI transcription service, then the Bulgarian text to a cloud AI translation service; each discards what it receives. NoteOwl stores nothing.
