Self loading cargo speech recognition

Hi all, I just got Self loading cargo and I have some problems with the voice recognition.
The documentation states, that it uses the Windows speech recognition. But when I enable Speech recognition in Windows 11 it just says this feature is going to be replaced soon and I should use voice access instead. Somehow I managed to activate it anyway and I set the Windows language to english.
Now in Self loading cargo it hardly works for me. The voice test does not recognize my voice at all. But during the flight the crew understands me sometimes, but most of the time not.
Does somebody have experience here, if it is possible to improve or train the speech recognition feature?
