Hi All,
Thanks to comments in flightsim.to I realised that I selfishly locked bushtrips to english only. English is not my native language so I don’t know why I didn’t think about it earlier. With new update I change importer to choose different language to import with bush trip if avaiable.
When you click on import and choose folder where bush trip new window will popup with language selection. Some of the community made bush trips may have mutliple language to choose but each language may have same translations as I saw so far.
I added also new option in settings to choose different voice for text-to-speech. This will list all voices installed in your system so if you need different one you need to install it in windows and will be listed there.
More updates in coming weeks 
Happy flying
