Hi there!
I understand that there is a much greater variation regarding the pronunciation of R than, for instance, in English. As I noticed in some Swedes' speech at least two different Rs (namely, a trilled variant and an approximant not unlike in English, the latter one appearing mostly before consonants (with which R is not combined to make a retroflex sound), I assumed it was not free variation but some sort of complementary distribution.
My question is: are the different R sounds of Swedish in complementary distribution, and if so, in which environments do they appear?
Thank you for your help in advance!
