発音合ってるって英語でなんて言うの？

You say the first name, 'Grizelda' but you are not sure if your pronounced it correctly:
"Did I pronounce your name correctly?"

Both of these answers are a good way of asking if you have pronounced someones name correctly. The first answer is a little bit more casual than the second answer.

All three phrases are used to ask if you have pronounced the name correctly. It is welcome of you to ask that to a foreigner because it shows good manners and your interest in being respectable to the person and they would appreciate that very much. The last last two phrases are more casual than the first, but all are accepted.
Hope this helps!
