I will look at why the charactere that Umlauts are not well pronounced. Do you have examples of other words? I will investigate :)

Danke für dein Feedback, das hilft mir wirklich weiter .

On the same topic, in Latvian all the characters with diacritics are stripped out completely. For example, "iedzīšana" is pronounced as "iedzana", making the audio pretty funny, though hard to understand.

I'm working on solving these pronunciation problems for the special characters if I unlock one everything else will follow. Don't hesitate to sign up to be kept informed!
