- No language surcharge — Czech costs the same as English at every Audexum tier
ElevenLabs does not list Czech in its core language set. Google Cloud TTS supports Czech at $16/1M. Audexum is €8/1M with a free tier — and renders the Czech ř correctly.
Czech SaaS and startup ecosystem
Prague's growing tech hub produces many apps that need Czech TTS for accessibility, onboarding narration, and user notifications — often on bootstrap budgets.
Audexum integrates as a single REST endpoint — no SDK required. Send your Czech text, receive WAV audio. The free tier (10K chars/month) covers prototyping; paid plans start at €4/month for 100K characters.
First Czech audio in 60 seconds.
The Czech language code is cs — pass it as the lang parameter.

Does Audexum render the Czech ř phoneme correctly?+
Yes. Czech ř (the voiced alveolar trill-fricative) is one of the hardest sounds for TTS models. Audexum renders it as the distinct Czech phoneme, not as a plain r, which is critical for intelligibility and naturalness.
Is Czech on the free tier?+
Yes. Czech is available on the 10,000 char/month free plan — no credit card required. Enough to build and demo a Czech-language accessibility feature.
Which TTS providers support Czech?+
Czech support varies. ElevenLabs doesn't list it as a core language. Google Cloud TTS supports it at $16/1M. Audexum is €8/1M with ř correctly rendered and a free tier for testing.
Can I switch between Czech and Slovak in the same API integration?+
Yes. Czech and Slovak use the same Audexum REST endpoint — just change the `lang` parameter from `cs` to `sk`. No separate API key or endpoint required.
Audexum supports 33 languages.
Switch language with one parameter — same API endpoint, same pricing.
See the full 33-language list in the API docs or on the multilingual TTS guide.
