which is not the case if you rely on the voice activity detector. So even if there are no no speech pauses , you can track the noise level. The only requirement is that you must have , in these five hundred milliseconds segment ,  you must have voiced sound at least. Cuz this  these will help you to  to track the  the noise level. Um. So what I did is just to simply replace the VAD - based , uh , noise estimate by this estimate , first on SpeechDat - Car  Well , only on SpeechDat - Car actually. And it 's , uh , slightly worse , like one percent relative compared to the VAD - based  estimates. Um , I think the reason why it 's not better , is that the SpeechDat - Car noises are all stationary. Um. So , u y y there really is no need to have something that 's adaptive
Mm - hmm.
and  Uh , well , they are mainly stationary. Um. But , I expect s maybe some improvement on TI - digits because , nnn , in this case the noises are all sometimes very variable. Uh , so I have to test it. Mmm.
But are you comparing with something  e I 'm  I 'm  p s a little confused again , i it  Uh , when you compare it with the V A D - based ,
