As in the words:
wahr /va:ɐ̯/
vergeht /fɛɐ̯ˈɡeːt/
Universität /ʔunivɛɐ̯ziˈtɛːt/ /ʔunivɛʁziˈtɛːt/
erlangen /ˌɛɐ̯ˈlaŋən/
and so on.
According to this answer and this wiki debate, a very slight version of R is pronounced in these words, but it's a little hard for non-native people to hear.
My question is, do you use these two symbols ʁ
and ɐ̯
interchangeably and I should prepare myself for a very slight (how much?) R in every word I see them, or there is a difference? I suspect ɐ̯
is not fricative but rather approximant, so the representation /ʔunivɛʁziˈtɛːt/
is incorrect maybe?
