This question already has an answer here:
Ok, there are two different ways to make the American r sound. They both think they are right and that the other is wrong.
- Make the r sound by retroflexing the tongue:
- Make the r sound by retracting the tongue:
Note: Both methods agree that the tongue should not touch anything in the mouth.
I think the retroflexed r is more natural. I have no way to make the retracted tongue because it is very uncomfortable for me.
So which one is correct?
