The correct estimation of the speech fonnant positions and evolution would help in several fields of the speech sciences, such as acoustic phonetics or speech recognition and synthesis. Linear Prediction (LPC) features naturally fit to the formant extraction. This article shows the results obtained starting from original algorithrns designed using LPC. The usual spectra (based on the Fourier Transfonn) show worse results than LPC in establishing the formant positions and evolution
