Czech is spoken by over 10 million people and produces a wealth of video content across education, media, and business. With its rich system of diacritical marks and complex grammar, Czech demands a transcription tool that truly understands the language. VidNotes, powered by OpenAI Whisper, provides accurate Czech video-to-text conversion on iOS, web at app.vidnotes.app, and via Chrome extension.

Czech-specific challenges VidNotes handles
Czech has linguistic features that make transcription genuinely difficult for tools not specifically equipped to handle them.
Diacritical marks (diakritika). Czech uses haceks (carons) on c, s, z, r, d, t, and n, plus an acute accent (carky) on vowels a, e, i, o, u, and y. These marks are not decorative — they change pronunciation and meaning entirely. "Cas" means time, while "cas" without the hacek is not a word. VidNotes preserves every diacritical mark accurately throughout transcription, summaries, and exports.
The r with hacek sound. Czech contains a sound found in virtually no other language — the r with hacek, a simultaneous trill and fricative. The famous tongue-twister "Strc prst skrz krk" (stick a finger through the throat) demonstrates Czech's ability to form entire sentences without traditional vowels. Transcription must correctly identify this unique phoneme.
Consonant clusters. Czech allows extraordinary consonant clusters that can challenge speech recognition. Words like "scvrnkls" (you shriveled up) or "ctvrt" (quarter) pack multiple consonants together without intervening vowels. VidNotes handles these clusters without inserting phantom vowels.
Seven grammatical cases. Czech nouns decline through seven cases, each with different endings for masculine, feminine, and neuter genders in both singular and plural. A single noun can appear in fourteen different forms. Accurate transcription must capture the correct case ending, as it determines the word's role in the sentence.
Spoken Czech (obecna cestina) versus written Czech. Colloquial spoken Czech differs significantly from standard written Czech (spisovna cestina). Most Czechs in everyday conversation use obecna cestina, which has different endings, vocabulary, and even vowel sounds. For example, "krasny" (beautiful) in standard Czech becomes "krasnej" in spoken Czech. VidNotes transcribes what is actually spoken rather than forcing a written standard.
Word order flexibility. Czech has relatively free word order due to its case system, meaning the same sentence can be arranged in multiple ways for emphasis. This flexibility can challenge transcription models that rely heavily on word order predictions.
