I know Standard German typically vocalizes 'r' in word-final and pre-consonantal contexts, but I know some dialects of German retain some form of 'r' in such positions. In Standard German the following words would be as follows:
"sterben" [ˈʃteːɐbən]
"Tier" [tʰiːɐ]
"Herd" [heːɐtʰ]
But for those that retain 'r' there, is it typically [ʁ] or some other kind of 'r', and what areas do this?
Also, another thing: my German professor said she once lived for a little while in a German town where the local dialect had an 'r' similar to the one found in most dialects of English, /ɹ/. She said she rented a room from an older couple who spoke the local dialect and when they called her "Frau Riebling," it would stand out to her since they used [ɹ] instead of [ʁ]. I forgot the name of the place--does anyone know where this occurs?
