Big part of the accent is sounding out each vowel. Which means talking a bit slower. So try pronouncing them slowly to yourself.
Assuming you legitimately want to change your current accent.
I'm not really trying to change my accent. Wherever I live is how I talk, like you see I learn off of how others speak.
My true accent before puberty forgeted me up speech wise was pretty clear but I talked to fast.
The one I picked up on is a pain in the ass at times.
Tire = Tar
Montgomery = Mont-gum-ree
forget = forget
I also skip vowels a lot.
'Son bitch!' - Son of a bitch
If I was to move to a place where people talked perfectly I would probably have issues there.
