Pronunciations!!!

One of my biggest pet peeves is getting corrected by an entire classroom of Kindergarten students for mispronunciation of names.  Now mind you, it doesn't bother me if the child whose name I am saying corrects me, in fact I appreciate their help in getting it correct.  What does bother me is when you have an entire class begin to shout at you.  First, I can't understand the chaos of all those voices and secondly, it just seems a little disrespectful.  I grew up in the Southern states and we were taught to always show respect to our teachers.  I would have never spoken up and corrected my teacher for anything even if it was saying my name incorrectly.  Kids today are different.  I've lived in the Northeast for over 30 years but my southern upbringing still creeps into my enunciation especially when it comes to some vowels.  Anyone who grew up in the south knows that pen and pin are pronounced the same.   Correct me if I am wrong Mr. E. or Cassie Stephens!!!  So sometimes these "different" names up north are a real challenge for me.  There is the student whose name I thought was pronounce like the thing a beauty queen wears on her head, a Tiara, you know?  It's not spelled that way but I thought that was what she said on the first day and now all the kids are correcting me.  I'm not sure how it is really pronounced.   And, then there is the cute little girl name Sawyer.  I think Tom Sawyer and pronounce it the same way but apparently that is not correct.  Still can't get that one right either.  That's just the beginning of the long list of names I continue to botch and repeatedly get corrected for.  So what is your take on all this?  How would you handle this in your classroom?  Feedback appreciated....help me!!!
