In my dissertation „The typical pronunciation failures of native-born Czech speakers and the
   methodes of elimination“ I wanted  to point out not only typical pronunciation failures, but
   also to clear up, why they rise, what is the reason, and mainly how is possible to prevent
   such failures or eliminate them as much as possible. On the basis of my knowledge I know, that
   is very impotant to articulate right. In case of wrong  articulation, the man has to be
   corrected by somebody else and should be explained to him, what is the¨right sound for this
   articulation. But most important is to clear up with Czech speakers, what exactly was
   articulated wrong, for case to prevent repeating of mentioned failure. I hope, my dissertation
   will fulfill its target, which was the orientation in most critical German speech sounds and
   others specification of German language, which creates the biggest problems to native-born
   Czech speakres.
