Key facts
- A word error rate of 12.86 for Bulgarian comes from a published paper on the large-v3 model, not from our own testing.
- The Bulgarian text comes back in Cyrillic, so search it with Cyrillic keywords rather than Latin spellings.
- Names of people and places are the usual weak spot, so compare them with a trusted spelling.
- The transcript is not translated into another language.
What a transcript looks like
[00:00] Speaker 1: Да започнем срещата. Първо ще прегледаме резултатите от миналата седмица, а след това ще планираме следващите стъпки.Meaning in English: Let's start the meeting. First, we'll review last week's results, then plan the next steps.

Published quality
| Language | Verdict | Published result | Notes |

These numbers come from published tests by other people, not from tests by Potok. Your own audio, with its noise, accents and microphone, will differ.
How to do it
- Send the recording. In @potok_now_bot attach the voice message, audio, video or paste a YouTube link.
- Mind the size. The limit is 2 GB per file. A long lecture can go through the Upload button in the bot's mini app.
- Turn on labels for conversations. Speaker labels and timestamps are optional. Enable them for interviews or meetings with several voices.
- Proofread the proper nouns. Scan the Bulgarian text for surnames, town names and brand names first, since those are most likely to be spelled differently.
- Export what you need. Download TXT, MD, DOCX or PDF to share, or SRT or VTT to subtitle a clip.

Common mistakes
| Mistake | What happens | Fix |
|---|---|---|
| Searching the transcript in Latin letters | Nothing matches because the text is written in Cyrillic. | Switch the keyboard layout or search with Cyrillic terms. |
| Skipping a check of names | A wrong surname can reach a published document unnoticed. | Compare names with an official source before use. |
| Sending a call with heavy background noise | Noise raises the error rate for Bulgarian as in any language. | Send the cleanest copy you have, recorded near the speaker. |

Frequently asked questions
How accurate is Bulgarian transcription?
Published tests of the large-v3 model give a word error rate of 12.86 for Bulgarian. That is another group's figure, not our measurement, and your audio may differ.
Does the bot return Cyrillic text?
Yes. The Bulgarian transcript is written in the Cyrillic alphabet, and exports keep that text as it is.
Can I send a Bulgarian video from YouTube?
Yes. Paste the YouTube link into the chat and the bot transcribes the speech, as long as the content fits the size limits.
Are speakers named in the result?
No. If you switch labels on you get numbers such as Speaker 1, and you can rename them in the exported file.
Is the Bulgarian text translated for me?
No. The transcript stays Bulgarian, since the bot does not translate transcripts into other languages.
