Sounds it gets confused with

Most pronunciation errors are not random — they are a substitution of the nearest sound the speaker already owns. These are the usual substitutions for u, and each one is a minimal-pair drill waiting to happen.

y

The substitution learners make for French u and German ü.

ʉ

Swedish and Norwegian u is central, not back.

What this means for learners

English /uː/ has fronted considerably in many modern accents, so English speakers must actively push the tongue back for a genuine cardinal /u/.

Teaching this sound

Describing a sound in words gets a student roughly half the way there. The other half is hearing it produced correctly, immediately after producing it incorrectly, with both versions available to replay. That is the argument for recording during the lesson rather than after it: the student leaves with your model of u attached to the actual words they got wrong, not to an abstract chart.
