Free Slovak transcription can be put to the test with one short clip. Published tests of others report a large-v3 word error rate of 8.4 for Slovak, the model Potok uses. Pick speech with long words and diacritics, and watch for Czech-looking spellings creeping into the text.

Key facts
- The score is a benchmark result from other people's recordings, so your own audio decides the real outcome.
- Slovak and Czech are close, and a tool can slide into a Czech form of a word.
- Soft consonants and long vowels carry marks that change the word.
- A tidy result on a read-aloud sample can still hide errors on spontaneous talk.
What a transcript looks like
[00:00] Speaker 1: Začnime stretnutie. Najprv prejdeme výsledky z minulého týždňa a potom naplánujeme ďalšie kroky.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 |
|---|---|---|---|
| Slovak (Slovenčina) | Recommended | word error rate 8.4% (large-v3, FLEURS) Canary-1B-v2 paper | Published tests show a low error rate for this language. |
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
- Select a clip with Slovak-only words. Pick words that differ between Slovak and Czech, since they show whether the text drifts.
- Open the bot. Open @potok_now_bot in Telegram and send the clip as a voice message, an audio file or a video.
- Check each mark. Go through accents and soft signs, and tick the ones that match the audio.
- Look for Czech spellings. Mark any word that reads as Czech and decide whether it matters to you.
- Go long if it works. For longer material send files up to 2 GB and export TXT, DOCX, PDF, SRT or VTT.

Common mistakes
| Mistake | What happens | Fix |
|---|---|---|
| Letting a Czech spelling pass | It reads as a minor oddity but is wrong for a Slovak reader. | List such words and fix them in one pass. |
| Testing with a news announcer | This is the easiest voice type there is. | Add a clip of everyday conversation. |
| Ignoring long vowels | The mark changes the word. | Check long vowels in every sentence. |
| Skipping numbers | Spoken numbers have several written forms. | Compare each number to the audio. |
