1. An interesting section extracting device, comprising: an anchor model storage unit storing anchor models that respectively represent features of a plurality of types of sound pieces; a specified time obtaining unit configured to obtain a specified time; a likelihood vector generating unit configured to calculate likelihoods for feature vectors that represent features of an audio signal, in one-to-one correspondence with unit sections of the audio signal by using the anchor models, and generate likelihood vectors having the calculated likelihoods as components thereof; and an interesting section extracting unit configured to calculate a candidate section, which is a candidate for an interesting section to be extracted from the video file, by using the likelihood vectors and extract, as the interesting section, a part or a whole of the candidate section including the specified time, wherein the interesting section extracting device extracts the interesting section interesting to a user from the video file with reference to the audio signal included in the video file such that the specified time is included in the interesting section.
