OK.
Oh , i Yeah , so what happened here is that , um , the overall improvement that they have with this method  So  Well , to be more precise , what they have is , they have these alignments and then they drop the beginning silence and  and the end silence but they keep , uh , two hundred milliseconds before speech and two hundred after speech. And they keep the speech pauses also. Um , and the overall improvement over the MFCC baseline So , when they just , uh , add this frame dropping in addition it 's r uh , forty percent , right ?
Mm - hmm.
Fourteen percent , I mean.
