I finally give up on mastering Standard American accent I took acting class when I was young. I needed to go to that class once or twice a week. It lasted 2 hours each time. My teacher could speak standard Madarin just as those news casters. We practised lots of tongue twisters to get a standard Madarin back then. I can still remember most of them even if it's 10 more years ago. I guess it's because I repeated them so many times that they are carved into my memory. Because of this experience, I can speak more standard Madarin than general Chinese people. It's also because of this experience, I'm too stubborn about standard pronunciation. I extend my pursue for standard accent to English. I've read lots of books and tried different methods to get so called Standard American accent. But I suddently find that there is no standard accent in American. It's not like British English and Madarin, there is no official documents tell you what is the standard accent. In a word, the more easily to understand you, the more standard your accent will be to American English native speakers. PS: If you'd like to be my language partner, please look at my profile.
