There 's two problems there. I mean  I mean , so  so the first is  that by doing LPC - twelve with synthesized speech w like you 're saying , uh , it 's   i i you 're  you 're adding other degradation.
Uh - huh.
Right ? So it 's not just the noise but you 're adding in fact some degradation because it 's only an approximation. Um , and the second thing is  which is m maybe more interesting  is that , um ,   if you do it with whispered speech , you get this number. What if you had  done analysis  re - synthesis and taken the pitch as well ? Alright ? So now you put the pitch in.
Uh - huh.
