Hi All, The LPC derived log area ratio coefficients are defined as gi=log(1-ki/1+ki) where ki comes from the Durbin's iterative method. I am wondering whether gi/ki (PARCOR coefficients) physically correponds to which side of the vocal tract. Suppose the LPC is of p order from 1 to p. Thanks in advance.

Hi Chuping, I'll try to say something as a short answer: kp lies closer to the glottis while k1 is closer to the mouth or to the mic.
