Read aloud has become useless on localized Windows 10. It will always pick the language of the operating system (in my case, German), so it will read all the resources as if they were written in German... Very funny, but unusable... 
I tried changing the default voice, changing the Logos language, restarting Logos etc. I just don't get Logos to use the EN-US or EN-UK voice...
So I assume, this is a bug...
