ABSTRACT:
A plurality of pitch period candidates are selected from a peak of correlation of a speech waveform in a current frame from which a pitch period is to be extracted, and a speech pitch is selected from the candidates by referring to a guide index which is precalculated based on pitch periods extracted in past frames. The guide index is an average of the pitch periods in the past frames.
