Hello everyone. My name is Kim studying at Russian Department. In my presentation, I'm going to criticize professor Lee's paper titled "Korean spelling errors of Korean learner's and ways for improvements."

Lee conducted an experiment based on the teenagers who are mother tongue is English living in North America. The goal of this experiment was figuring out the reasons why these students have had spelling errors in Korean. Also he proposed some solutions to improve the errors. Professor Lee thinks that they have different learning processes between heritage learners and foreigners.

First of all, teenage Korean learners whose parents are both Korean, obviously they have more opportunities to be exposed to an Korean speaking environment than others.

Second, even though Korean is their second language, the teenagers have the most similar accent of Korean one. Because of this, despite their unclear pronunciations, it sounds fluent.

Last, those students who have abilities to listen and speak properly can't write Korean without mis-spelling. It's due to the fact that they haven't got proper education for writing which leads them mis-spelled.

I want to raise an objection to his second point. What does it mean having 안정적인 억양? (never mind using Korean here, it's needed to be here) Does it mean having the most similar sound to Korean accent? Are there any standard accent we can tell easily?
