Yes , I 'm playing. Um  so I wanted to do this experiment to see um  uh what happens if we try to uh improve the performance of the back - end recognizer for the Aurora task and see how that affects things. And so I had this um  I think I sent around last week a   this plan I had for an experiment , this matrix where  I would take the um  the original um the original system. So there 's the original system trained on the mel cepstral features and then com and then uh optimize the b HTK system and run that again. So look at the difference there and then uh do the same thing for  the ICSI - OGI front - end.
What  which test set was this ?
This is  that I looked at ?
Mm - hmm.
