Hi there guys. I thought these videos might help your questions. They were part of an experimental pinyin browser tool, which I will see if we can get made. In the meantime, I will see what I can do from my end to allow you to see all the noised spoken by @daxulaoshi.
@thejco, We only had the pleasure of filming with Professor Xu for two days before he had to go abroad. The Say It Right series is not intended to be a complete solution to all of Mandarin sounds, but a great starting-off point for all beginner and intermediate students to correct any bad habits
