2). Make the verfication score results dividied into four parts. --"Real True Speaker"/"Sensitive True
Speaker"/"Sensitive Imp Speaker"/"Abosulte Imp Speaker".
3). Re-score for the four parts on the cohort set.
4). Score ranking for each part and draw score-rank distrubution diagrams.
1. Go on the task1 to explore the inherent law of re-scoring results and use the cohort set to
reduce the error rate on the "Sensitive True Speaker"/"Sensitive Imp Speaker".
