I  I  I really wonder though.
Mm - hmm.
I mean we 've had these discussions before , and  and one of the things that struck me was that  uh , about this line of thought that was particularly interesting to me was that we um  whenever you condense things , uh , in an irreversible way , um , you throw away some information. And , that 's mostly viewed on as a good thing , in the way we use it , because we wanna suppress things that will cause variability for uh particular , uh , phonetic units. Um , but , you 'll do throw something away. And so the question is , uh , can we figure out if there 's something we 've thrown away that we shouldn't have. And um. So , when they were looking at the difference between the filter bank and the FFT that was going into the filter bank , I was thinking " oh , OK , so they 're picking on something they 're looking on it to figure out noise , or voice  voiced property whatever. " So that  that 's interesting. Maybe that helps to drive the  the thought process of coming up with the features. But for me sort of the interesting thing was , " well , but is there just something in that difference which is useful ? " So another way of doing it , maybe , would be just to take the FFT uh , power spectrum , and feed it into a neural network ,
