I natively speak Flemish (Dutch). We trill the R.
I just had a 7-lesson course (over video chat with an American lady) to improve my accent towards Standard American English. According to the test I improved greatly, but there is just one particular sound I still have great trouble with.
r gets anywhere near a
th, I get a tongue tap (as in /R/). I can now usually manage to get
thr right, but
r th still often fails, at least if the th is a /ð/.
north are no trouble, but
for the is harder, and one I can NEVER even get right (at speed) is
bother them. I've heard examples of people saying those words right after each other while still clearly pronouncing that /ɹ/ and /ð/, and I want to know how!
My trouble with
bother them is that after the first
th, my tongue is moving backwards to produce the
r, and then it has to travel too quickly back to the front for the second
th, tapping my palate along the way. It seems physically impossible to avoid that.
It's probably mostly related to how I pronounce /ɹ/. My previous habit was to twist my tongue (placing it sideways, touching both top and bottom of the mouth with either sides). While this actually sounded fine, I figured learning the 'right way' might improve my chances of pronouncing composite consonants more correctly. So I'm now trying to always pronounce it by having the sides or my tongue press against my upper molars instead, pointing the tip upwards but not touching. That "the way", right?
So in short:
I would value any very specific tips/explanations on pronouncing
bother them correctly, i.e. with /ɹð/ but without tapping the palate.
