Epoch extraction from linear prediction residual
Research Area: Uncategorized Year: 1978
Type of Publication: In Proceedings  
Authors: T. Ananthapadmanabha, B. Yegnanarayana  
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.
