Abstract

This paper develops a formant tracking technique based on Fourier ridges detection. This work aims at improving the performance of formant tracking algorithms. In this method, we have introduced a continuity constraint based on the computation of the centre of gravity for a set of formant candidates, which leads to link a frame of speech with its neighbours and thus improves the robustness of tracking. The formant trajectories obtained by the algorithm proposed are compared with those of a hand edited formant Arabic database, created especially for this work, and those given by Praat with LPC data.

<abstract xml:lang="en">This paper develops a formant tracking technique based on Fourier ridges detection. This work aims at improving the performance of formant tracking algorithms. In this method, we have introduced a continuity constraint based on the computation of the centre of gravity for a set of formant candidates, which leads to link a frame of speech with its neighbours and thus improves the robustness of tracking. The formant trajectories obtained by the algorithm proposed are compared with those of a hand edited formant Arabic database, created especially for this work, and those given by Praat with LPC data.</abstract>
