Hello,

would it be possible to add Czech TTS language option to the Audio out node?

Thank you in advance and have a great day!

Hi - the TTS uses the built in HTML5 support of your browser - using the call - window.speechSynthesis.getVoices();

Can you see if the example here - does contain Czech ? [https://developer.mozilla.org/en-US/docs/Web/API/SpeechSynthesis/getVoices](https://developer.mozilla.org/en-US/docs/Web/API/SpeechSynthesis/getVoices)

On my version of Chrome it says that Zuzana is cs-CZ so it should be possible.

If that doesn't have Czech then I don't know how to add it.
