Yeah.
so if you look at   Suppose you look at first and second - order cepstral coefficients for some one of these kinds of things and you find that the first - order is much more effective than the second ,  and then you look at the third and there 's not  and not too much there ,  you may just take first and second - order cepstral coefficients ,
Yeah. Yeah.
right ? And with LPC , I think LPC per se isn't gonna tell you much more than  than  than the other , maybe. Uh , and uh on the other hand , the LPC residual , the energy in the LPC residual ,  will say how well , uh  the low - order LPC  model 's fitting it , which should be  pretty poorly for two two or more  people speaking at the same time , and it should be pretty well , for w for  for one.
