That's going to be a bit difficult I think. I know some Chinese people and there is no way i could properly explain the sounds of their names in the way pronunciations are written on this site.
A Chinese girl form my school told me that there are more ways to say sounds, like the Q (like in Qing) and Ch (like in Ching) would both be CH in the transcript, but they are in fact different sounds. (She explained them to me, and after trying several times, I got it right, one of them is more said using the bottom part of the mouth and the other more with the upper part). Also the intonation is not possible then, which could lead to people saying a completely different word.
But if there would be a way to explain them I'd be very interested in seeing all the pronunciations of them :) (maybe the 4 way of intonation could be given a number or something like that?)
