Abstract

An interpretation of linear prediction (LP) residual is presented by considering the effect of following factors: shape of glottal pulse, phase angles of formants at the instant of excitation, inaccurate estimation of formants and bandwidths, zeroes in vocal tract system transfer function. Effect of improper phase cancellation on the accuracy of estimated epoch position is also discussed. A method for unambiguous identification of epochs from LP residual is presented.
