Measured on 20 FLEURS clips, 2026-09-05. That figure is for Belarusian spoken on its own; accuracy on mixed speech is measured separately and not claimed here. Full method, all 59 languages

Belarusian is not treated as an accent

Two close languages, one with far less training data behind it — which is exactly the case where a model quietly resolves everything into the larger one.

Distinctly Belarusian letters survive

ў and і are transcribed as themselves rather than normalised to their Russian neighbours.

Timing measured, not estimated

Word-level alignment against the audio rather than an estimate that drifts across a long clip.

Trasianka — two languages in one sentence

Trasianka mixes Belarusian and Russian in a single sentence, and the pull toward Russian is not just linguistic — it is statistical. There is far more Russian in any model's training data, so the cheapest thing for a transcriber to do is to hear Russian everywhere. Transcribing against the audio rather than against expectation is what keeps the Belarusian.

Questions

Will Belarusian words be turned into Russian ones?+

They are transcribed as spoken. The drift toward the larger language is the specific failure this is built to resist.

Are ў and і handled?+

Yes — they are distinct Belarusian letters and are transcribed as themselves.

What can I export?+

Subtitles burned into the video for Reels, TikTok and YouTube, or SRT and VTT files.
