Try a Czech line
Dobrý den. Vítejte v Qefro Voice Studio. Tento delší odstavec není jen krátký pozdrav. Je tu vyprávěna celá scéna, abyste slyšeli pauzy mezi větami, váhu slov a závěrečný tón. Ranní trh se pomalu probouzel. Prodavač rovnal nové květiny, vůně čaje vyšla do uličky a děti se před školou jednou ohlédly. Dobrý hlas tyto obrazy neuspěchá. Po poslechu změňte dvě slova a vytvořte zvuk znovu.

Linguistic notes & pronunciation considerations
Czech is characterized by fixed stress on the first syllable of each word, long and short vowels (á, é, í, ó, ú, ů, ý), and unique consonants including the raised alveolar trill (ř) and palatalized stops (ď, ť, ň, ě). Supertonic-3 preserves vocal resonance across consonant clusters (such as strč prst skrz krk).

Developer API cURL snippet
Automate Czech voiceover generation directly in your application backend:
curl -X POST https://voice.qefro.com/api/v1/tts -H "Authorization: Bearer YOUR_API_KEY" -H "Content-Type: application/json" -d '{"text": "Dobrý den všem!

How does Qefro handle the Czech letter ř?
The Supertonic-3 acoustic engine is trained on native Czech speech data and correctly articulates the distinct Czech fricative trill (ř) in both voiced and unvoiced positions.
What audio format is best for Czech YouTube narration?
Download lossless WAV audio for maximum clarity in video editing timelines; or use OGG for web streaming.
Can I convert Czech numbers and dates into speech?
Yes. Standard Arabic numerals (e.g., 2026, 15 %) are naturally vocalized into Czech cardinal and ordinal phrasing.
Is there an API to automate Czech voiceover generation?
Yes. Our paid API tiers provide REST endpoints (POST /api/v1/tts) with bearer key authentication and JSON formatting.
