ご質問どうもありがとうございます。
様々な表現があると思いますが、いくつか自然な表現を紹介します。
1. Did I pronounce that right?
私の発音は正しかった？
2. Was the pronunciation correct?
私の発音はあってますか？
お好みに合わせて使い分けてみてください！
ご参考にしていただければ幸いです。
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!
