Alas, that isn't as true as German's tell me it is, I find.
"Weg" <- how do you pronounce this?
"Geh weg" (go away) "Der Weg ist da drüben!" (the path is over there)
"Weg" <- how do you pronounce this?
"Geh weg" (go away) "Der Weg ist da drüben!" (the path is over there)
You missed "Gehweg" (sidewalk) though. :^)
I don't know what you're trying convey in your examples though, because all the example have consistent pronunciation. Inconsistence pronunciation often because it is borrowed words from French (das Experiment (Ex-pe-ri-mo'n?)) or English (das Schedule, informal vocab.)
But German pronunciation is 80% simple and regular at least whereas English is more like 80% complicated and irregular.
