i'll listen to it more and feedback. thanks.

i've come up with a recording on this and will need time to edit it and will post it asap, i think i've get something from this, ie, the pronounciation of /dr/ from /d + r/ ... and that of /tr/ from /t + r/ ... i've watched a little girl sounding that way /t + r/, it might be the natural way of sounding it. 
Then, it might be the same case with /d + r/ scenario. 

所有跟帖： 

• dr 就是d+r 发快了的和音， 老外说慢了， 有时会把d和r 分的比较明显。 -DirtyTalk- ♂ (0 bytes) () 05/14/2013 postreply 10:29:21

• 纠正一下，dr 的快发音是/d3/+r， 非常慢发音是d+r -DirtyTalk- ♂ (0 bytes) () 05/14/2013 postreply 10:48:13

• 是的，听到过。慢读和快读发音变化巨大。 -yingyudidida- ♂ (0 bytes) () 05/14/2013 postreply 11:03:25
