I was mocked fun of in class this morning because I pronounced "tamago" with "ɳ" sound (like ɳ sound in "singer" instead of "g" sound (like "go") which is taught by teachers. I've imitated the voices of "Minna no nihongo" audio files.
So, which one Japanese prefer to use? Is it okay if I pronounce that way? It's more convenient to my mouth when saying "ɳ".
One more question, I found "ra ri ru re ro" is the most difficult consonant to say, I've watched some of youtube videos and I heard it's sometimes like "l sound", sometimes "r" sound or even "d sound", if I had to pick one of three sounds, which one is more easy for Japanese to understand?
