Abstract
The paper describes an algorithm for estimating the pitch and formantspsila center frequencies and bandwidths with the use of instantaneous complex frequency (ICF). ICF for each formant is computed from the analytic signal, obtained by filtering speech signal with a passband complex Hilbert filter, which additionally separates the analyzed formant from the speech signal.
