I read this comment on Youtube.
is it possible that the sound / ɹ / tends to close the vowels that precede it? For example, at least to me, [very] / ˈvɛɹi / sounds more like / ˈveɹi /, [more] / ˈmɔɹ / more like / ˈmoɹ /, [chair] / t͡ʃɛəɹ / more like / t͡ʃeəɹ /, etc. Is it at least partially correct?
The maker of the video answered:
I think the R does close the vowel in some cases, yes! In particular with words like 'more'. The other examples there may be a closed a bit, but I think it is also possible and common for the vowel to stay more 'open'.
Like in the comment I hear [very] as / ˈveɹi /, [more] as ˈmoɹ /, [chair] as / t͡ʃeəɹ /. So which pronunciations are the most common in General American?
