+Assum you executed g2p test twice, the WER rate have some gap, you would like to see what sentences error cause your rate up.
+so you may get test result ( exp/g2p )into two directories, as exp/prefolder and exp/curfolder
+run this program as  "python compare_badcase.py prefolder curfolder"
+then you will get diffrences between two run, uuid, phonetics, chinese samples
+
+examples: python compare_badcase.py  exp/g2p_laotouzi  exp/g2p
+in this example:  exp/g2p_laotouzi  and  exp/g2p  are two folders with two g2p tests result
