Abstract
Input sound information is converted to digital sound data, and characteristic parameter values are extracted from the digital sound data. Based on the characteristic parameter values, a judging unit produces a judgement result indicating whether the current section is a significant or insignificant section and its continuation length. If the continuation length is shorter than the predetermined length, a correcting unit reverses the judgment of whether the current section is a significant or insignificant section and sums up the continuation length of the current section and continuation lengths of the adjacent sections, to thereby produce a single section data.
