摘要

The present invention makes it possible to advantageously identify a song that corresponds to an input sound signal. A continuously inputted sound signal is converted into a predetermined feature value series. A verification process between the feature value series and the song information is carried out in sequential fashion as soon as the feature value series accumulates a predetermined amount, and a song in which the degree of verification is larger than a threshold value is ultimately identified. In this case, conversion of the continuously inputted sound signal into the predetermined feature value series and the verification process between the feature value series and the song information are carried out in parallel fashion. It is therefore possible to carry out song identification with excellent real time characteristics.
