I am a teacher and writer. My strength is in grammar. My boss from Korea wants me to teach a young student pronunciation. The boss said she is already fluent in English, but wants an American accent. I think this is the tougher side of teaching. I am familiar with the international phonetics. If my student can use that , I will demonstrate sounds for her.
While teaching, I saw and used textbooks that describe mouth parts and how to shape them to form sounds. Even when using this, my students did not gain much from my instruction. I need a better technique. I think listening to examples is part of the best way, but that is not enough.
What can I do to teach a Korean student the American pronunciation?
(I hope none of the future students asks me to teach British pronunciation. I'm not from England. I simply can't teach it correctly.)
