16:46 "playing" sounds a bit Australian with the diphthong being closer /aɪ/.
16:29 "experiment" is /ɪkˈspɪɹ.ə.mənt/ with /ɪ/ vowel. I thought it should the cheer-chair merger, but wiki says the merger merges towards the "chair" vowel, not the opposite.
18:01 "best" vowel is lowered similar to the "playing" diphthong.
18:09 "amp", 2:03 "band" have æ-raising (actually not sure about this one)
18:22 "get" sounds like "git"
16:27 "then" doesn't feature the pin-pen merger, and sounds rather like "than". The vowel is lowered again.
2:00 - 2:05 I really can't tell if "all" and "call" have /ɑ/ or /ɔ/, and next to the word "moderate" with a clear /ɑ/, it sounds like his "call" vowel is backed, but not really an /ɔ/, thus I can't tell if he has the cot-caught merger 😭
Just based on the absence of the pin-pen merger and presence of æ-raising, I would put him somewhere around northern Michigan. What do you think?
