ABSTRACT:
In a formants extracting method capable of precisely obtaining formants as resonance frequencies of voice with less computational complexity, the method includes searching a maximum value by a spectral peak-picking method, judging whether the number of formants corresponding to a zero at the obtained maximum point are two, and analyzing a pertinent root by roots polishing when the number of the formants are judged as two. The number of the formants are judged by applying Cauchy's integral formula, wherein Cauchy's integral formula is not applied repeatedly but only once at a surrounding portion of the maximum value in a z-domain.
