I have tried different providers. German is not so easy for the systems. Some tested systems were very cumbersome, often failed, and the voices sounded very unnatural. I then bought a code to test the system. The result is excellent. I can upload long texts and the system delivers good results rapidly. I then bought more codes. My wish: to be able to upload my own music for the background. I am also happy that a white-label player can be used. Keep it up!
