PROBLEM TO BE SOLVED: To provide a method and an apparatus for determining an instantaneous frequency and an instantaneous bandwidth about speech resonance of a speech signal.SOLUTION: A method includes: a step 505 for receiving a speech signal having a real component; a step 510 for performing filter processing the speech signal so as to generate a plurality of filter processed signals such that the real component and an imaginary component of the speech signal are reconstructed; and a step 515 for generating a first estimated frequency and a first estimated bandwidth about speech resonance of the speech signal on the basis of both a first filter processed signal of the plurality of filter processed signals and a single-lag delay of the first filter processed signal. |
