Phase Coinpensation in All-Pole Speech

General methods are discussed for estimating a phase iodel in the context of all-pole analysis of speech. An optimal estimator is presented when the phase model is a strict all-pass filter. It is shown that the solution to this estimation problem is very close to established methods of n. As a complement. DFT-methods for the are briefly discussed and evaluated. e experience from using the algorithms is esented. including results for applications as glottal-inverse ring and speech coding.
