Is Bulgarian supported by your engine?
Not by ours. We accept 99+ languages, and the service contract is explicit. Bulgarian audio belongs to a service that lists Bulgarian.

In short
Bulgarian is not one of our 99+ languages: we run 99+ languages only. AssemblyAI rates Bulgarian in the class of 10–25 % word error, Sonix lists it among 54 transcription languages, and Descript only translates captions into Bulgarian. Our file limit is 30 minutes.
The case
The market handles Bulgarian with numbers
Bulgarian is one of the languages the market handles with numbers rather than adjectives, and the numbers are good: AssemblyAI puts Bulgarian in the class below 25 % word error, next to Czech, Danish and Romanian. We keep our own list short, 99+ languages and 99+ languages, and we publish the class tables we read instead of a marketing sentence.

How to get a Bulgarian transcript

Check the language list of a vendor
Sonix publishes 54 transcription languages and Bulgarian is on it, together with a Bulgarian page in its sitemap. One list and one page for the same language.

See what Descript offers
Bulgarian is not among the 25 languages Descript transcribes. It is one of 61 for caption translation and one of 30 for dubbing, which is a different job.

Know what a class is not
A word-error class is the vendor's own measure of its own engine. It says nothing about your recording: a noisy room in Sofia is still a noisy room.

Send the 99+ languages file
Our part of the job: up to 30 minutes, $0 for 3 files a day, 6 export formats. Everything comes back with timecodes and, on request, the speakers named.
