Well , I cannot  you cannot hear beca well , actually what I d did not say is that this is not in the FFT bins. This is in the mel frequency bands. Um  So , it could be seen as a f a  a smoothing in the frequency domain because I used , in ad mel bands in addition and then the other phase of smoothing in the time domain. Mmm. But , when you look at the spectrogram , if you don't have an any smoothing , you clearly see , like  in silence portions , and at the beginning and end of speech , you see spots of high energy randomly distributed over the  the spectrogram.
Mm - hmm. Mm - hmm.
