Hi , I need some help regarding getting Cepstral coeffs from LPC coeffs. I have found 2 variation for the algo to do this. 1) One algo (given in fundamentals of Speech recogntion by Rabiner/Juang) says that the initial cepstral coeff is the residual gain term as calculated in the LPC phase. 2) Another algo that I found says that the first cepstral coeff is the first LPC coeff. I have a confusion regarding this. Will somebody please explain this? Thanks and reagards, Abhijeet Joshi
