When learning a foreign language, learners try to avoid their native accent. But native speakers tend to think it adorable. If a foreigner speaks mandarin without any accent I would consider it weird. 我想把英语说得跟她一样,但在外国人看来说成那样不会奇怪吗?http://contest.i21st.cn/article/speaking/2058_1.html
加拿大的大山普通话说的很好,带着点北京腔,但我感觉怪怪的。其实学语言没有个人口音是很难的,只能试着去避免。个人认为只要地方口音不要太重南方比北方的儿化音好听【好吧是因为我是南方人】台湾腔和标准普通话有点差别但挺好听的……
