Webster even invented a special symbol (a superscript "y") for this, but no Russian can hear anything like that.
One interesting indication of it may be this: in Japanese, I very clearly hear their 'z' line sounds as 'dz'-s, and all Russian books on Japanese instruct to pronounce it as 'dz'. On the other hand, all English books I've seen just say that the Japanese 'z' is just "z like in zoo", which seems totally wrong to me. Our native language affects our sound recognition a great deal.
