How to Fix Mispronunciation Issues in Audiobook Maker 3.3 with German Text?

[Baysang]

I'm using Audiobook Maker 3.3 with German input text like:

"Wie haben Sie heute Nacht geschlafen?
Ja, bitte! Können Sie mir einen Tee bringen?"

However, some German words like "Wie" and "Ja" are pronounced in English rather than German. Additionally, some words produce strange or distorted sounds. There are several other similar pronunciation issues. Could you guide me on how to resolve this? Thank you!
