Uh , second thing is the initialization of the  stuff. Actually ,  uh what we were doing is to start the recursion from the beginning of the  utterance. And using initial values that are the global mean and variances  measured across the whole database.
Right. Right.
And Pratibha did something different is that he  uh she initialed the um values of the mean and variance  by computing  this on the  twenty - five first frames of each utterance. Mmm. There were other minor differences , the fact that  she used fifteen dissities instead s instead of thirteen , and that she used C - zero instead of log energy. Uh , but the main differences concerns the recursion. So.  Uh , I changed the code uh and now we have a baseline that 's similar to the OGI baseline.
OK.
