What to expect translating Czech and English 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.

English keeps a fixed subject-verb-object order and no grammatical gender, so it is often the structurally simpler side of a pair. Recognition likewise covers the English of North America, the United Kingdom, and far beyond.

The transcript shows each side in its own writing system: the Latin alphabet with diacritics for Czech, the Latin alphabet for English. Because Whisperr auto-detects which of the two languages is being spoken, Czech to English conversations flow in both directions without switching anything by hand.

Czech to English translation FAQ

Can I translate Czech to English by voice in real time?+
Yes. Whisperr listens to spoken Czech and shows or speaks the English translation live, with about 0.2 seconds of latency — in person, on calls, or over video.
Does it translate both directions?+
Yes. It auto-detects Czech and English and translates each into the other automatically, so a two-way conversation just flows.
Where can I use it?+
Face-to-face (microphone), on video calls (browser tab capture), and while watching video (floating subtitles on iOS & Android or tab capture).
Which devices are supported?+
Native iOS, iPad, Mac, and Android apps, plus a web app and a Chrome extension. One login works everywhere.
Is it free?+
You can start for free. Unlimited real-time use is available on a low flat annual plan, with no per-minute metering or per-language caps.
Which Czech varieties does Whisperr understand?+
Whisperr understands Common Czech, Bohemian, and Moravian varieties; speech recognition adapts to accents automatically, with no setup.
How different are Czech and English?+
Czech is a West Slavic language and English is a West Germanic language; grammar and word order differ, which is why literal word-for-word translation reads awkwardly. Whisperr translates complete phrases, so the output sounds natural in both.
