In German, the vowels between schwül and schwul were really difficult to do for me as an American English speaker. I couldn't ever hear the difference between rounded and unrounded vowels. American English vowels are only rounded in the back. u and o (and in the East the au in caught).

We have only seven vowel sounds. A i u and open / closed e o. But different parts of the country often use only one of the two e and o sounds.
