Mm - hmm.
Basically , I think that  that this test was a little bit bogus because of the data and uh essentially  there were these arbitrary decisions made , and  and everything. So , so  so this is  so this is where it is. So what we are doing at OGI now is uh uh uh working basically on our parts which we I think a little bit neglected , like noise separation. Uh so we are looking in ways is  in uh which  uh with which we can provide better initial estimate of the mel spectrum basically , which would be a l uh , f more robust to noise , and so far not much uh success.
Hmm.
We tried uh things which uh a long time ago Bill Byrne suggested , instead of using Fourier spectrum , from Fourier transform , use the spectrum from LPC model. Their argument there was the LPC model fits the peaks of the spectrum , so it may be m naturally more robust in noise. And I thought " well , that makes sense , " but so far we can't get much  much out of it.
