Bug in Text to Speech (German)

I am not sure if this is a bug in Scrivener or in Windows, but when I use the built-in TTS of Scrivener (Edit - Language - Speak), it “autocompletes” some words (IE “selbst” is read as “selbständig”), what is quite confusing.
Can anybody reproduce this?

This is due to the text-to-speech engine you are using. Try switching or installing a different text-to-speech engine, which might help in your case.
