Spelling the model has to guess from context
Several Czech spelling choices cannot be heard at all, so the speech model picks them from the surrounding words. It gets the common cases right, but these are the places where a careful reader still finds slips.
- i or y: byli (were) and bili (beat), mýt and mít, výr and vír sound the same. Check every word where the meaning depends on it.
- Past tense endings: ženy přišly and muži přišli are pronounced alike. In a mixed group the model may pick the wrong ending for the subject.
- mě or mně, and s or z: the pronouns and prepositions are spoken the same way, so look at s sebou, z domu and similar phrases.
- Commas: Czech requires a comma before most subordinate clauses (že, který, protože, když). Fast speech sometimes comes out with these commas missing.
Capital letters, numbers and dates
Czech capitalizes less than English. Months, days and adjectives of nationality stay lowercase (listopad, pondělí, český), while a noun for a person takes a capital (Čech, Pražan). In the names of institutions only the first word is capitalized: Univerzita Karlova, Ministerstvo zdravotnictví. Street names such as Na Příkopě keep the capital on both parts. English-style title case in a transcript is a sign to edit.
Numbers follow Czech conventions once you edit them: a decimal comma (3,5), a space as the thousands separator (12 500) and the currency after the amount (250 Kč). Dates are written with dots and spaces, 4. 11. 2026, and an ordinal takes a dot (2. patro). Time can be 14.30 or 14:30, so choose one form for the whole document.
Spoken numbers come in two shapes. Pětadvacet and dvacet pět both mean 25, and the transcript may show either form, words or digits. If the figures matter, read them against the audio.
A checklist before you publish
Read the transcript once with the audio playing, then go through this list. Clicking a line replays that moment, so each check takes seconds.
- Names of people, villages, companies and brands are spelled the way their owners spell them.
- Each i or y and each past-tense ending fits the subject of the sentence.
- Months, days and nationality adjectives are lowercase.
- Numbers, amounts in Kč and dates use one consistent format.
- Colloquial forms are either kept on purpose or changed to standard Czech everywhere, not halfway.
- English terms such as call or deadline are spelled consistently.
Common Czech recordings
Typical uploads include video recordings of a zastupitelstvo (town or city council) session that a town wants to publish as text, team meetings that need a zápis, university lectures recorded in Teams, interviews for a seminar paper, local podcasts, and radio-style conversations people want to quote. Families also bring cassette recordings of grandparents that were digitized to MP3.
For a council meeting or a long lecture, export DOCX and edit it into minutes. For a podcast or video, export SRT or VTT for subtitles. Timestamps and speaker names can be switched on or off for each export, and speaker labels showing who said what come with paid plans or a Minute Pack. Recordings are never used to train AI models.
