What to expect translating Czech and Slovak live

Czech splits into a formal written standard and everyday "Common Czech" that sound like two registers of one language. Whisperr’s speech recognition covers the Czech spoken across the Czech Republic.

Slovak is close enough to Czech that speakers usually understand each other, so auto-detection has to key on the systematic differences between the two. Recognition likewise covers the Slovak of Slovakia.

Both languages are written in the Latin alphabet with diacritics, so the two sides of the transcript read naturally next to each other. Because Whisperr auto-detects which of the two languages is being spoken, Czech to Slovak conversations flow in both directions without switching anything by hand.

Which Czech varieties does Whisperr understand?+

How different are Czech and Slovak?+
