| Abstract(in English) | We discuss a formant estimation method by using an ARMA pre-filter, and presented the estimation method so that the frequency charateristic of ARMA filter can be good agreement the spectrul tilt of the sound spectrum in a frame. The estimation method include the conjugated gradient method with a constrained condition. We show that the spectrum can be flattened with optimal compensation for vowel sounds. In addition, it is very dificult to avoid the flase formant in LPC analysis, but we propose the method to solve this problem and reduced the estimation order by 3 order. |
