WAY too fast on the first couple words.. just sounds like chi chi nay..
Native speakers have no problem with it. That's the problem...this is set up for native speakers who don't need no stinkin' Tips and Notes or slow things down with a turtle button. It's all tiger speed.
It sounds fine to a native speaker, but he says "Chương trình" quite fast.
Some commenters say they hear better with eyes closed. I find that repetition also helps. I repeat the audio over and over again until I start to hear the pronunciation. If I still can’t hear it after 3 to 5 times, I look for the pronunciation elsewhere or move on and make a mental note to find another pronunciation in a later DL lesson.
Since different pronunciations exist in real life, I am grateful for the variable pronunciations we learn in DL.
It took me about 60 to 100 hours of DL before I started to hear the pronunciations that the diacritical marks, diphthongs, and spellings convey. The more I study, the more I learn.(I have not yet figured out how to convey the difference between these two meanings of học. Also as in, I study but I do not learn.)
I "Follow" these discussions to listen over a couple of days in between stuff.With practice, you will eventually get it. I suspect it takes time to rewire our noodles with this language.
