摘要
A pitch frequency estimation device capable of estimating a pitch frequency precisely while reducing the computational complexity required for the estimation of the pitch frequency. In this device, a spectrum extraction unit (104) extracts a pitch-harmonized spectrum from a voice spectrum. A spectral average calculation unit (106) calculates the average of the power of the pitch-harmonized spectra extracted by the spectrum extraction unit (104), in a manner to individually correspond to a plurality of pitch frequency candidates. An estimation unit estimates the pitch frequency by using the average valve calculated by the spectral average calculation unit (106).
