2004
In the information detection apparatus of the present invention (1), the audio type identification section (11) for identifying and classifying the audio signal in a predetermined period of information sources such as the type of music and speech, memory device / storage medium (13 ) identified by the information recording. Identification frequency calculation section (15) calculates, for each unit of time longer than the frequency interval of each of the identification of said predetermined unit Time interval start / end judgment section (16) when the frequency has a first type identification times becomes greater than or equal to a predetermined threshold value and equal to or greater than a predetermined threshold value has continued for a predetermined period when detection of the start of a continuous interval of the type, and when the kind of identifying the first frequency has become equal to or less than a predetermined threshold value and equal to or less than a predetermined threshold value has continued for a predetermined period of time when detecting the end of the successive intervals species.
