Automatic estimation of voice source parameters

Automatic parametrization of voice source signals: a novel evaluation procedure is used to compare methods and test the effect of low-pass filtering

There is a need for automatic methods for parametrization of the voice source signals. Representatives of the two types of methods that have been used most often for parametrization were tested and compared. For this purpose a novel evaluation procedure is proposed which makes it possible to perform the numerous tests needed for a detailed comparison of the methods. This evaluation procedure re...

Testing Two Automatic Methods for Estimation of Voice Source Parameters

Spectral methods for voice source parameters estimation

A spectral approach is proposed for voice source parameters representation and estimation. Parameter estimation is based on decomposition of the periodic and the aperiodic components of the speech signal, and on spectral modelling of the periodic component. The paper focusses on parameters estimation for the periodic component of the glottal ow. A new anticausal all-pole model of the glottal ow...

Automatic parametrization of differentiated glottal flow: Comparing methods by means of synthetic flow pulses

The automatic parametrization of the first derivative of glottal flow is studied. Representatives of the two types of methods used most often for parametrization were tested and compared. The chosen representatives are all based on the Liljencrants–Fant model. As numerous tests were needed for a detailed comparison of the methods, a novel evaluation procedure is used which consists of the follo...

Automatic voice-source parameterization of natural speech

We present here our work in automatic parameterization of natural speech by means of a pitch synchronous source-filter decomposition algorithm. The derivative glottal source is modelled using the Liljencrants-Fant (LF) model. The model parameters are obtained simultaneously with the coefficients of an all-pole filter representing the vocal tract response by means of a quadratic programming algo...
